From e7875491fc7be96c4b87909b4c115a7d181be686 Mon Sep 17 00:00:00 2001 From: kould Date: Tue, 27 Oct 2026 09:29:49 +0800 Subject: [PATCH 01/20] fix(storage): prevent lost updates on RocksDB and drop read committed - RocksDB transactions (pessimistic and optimistic) now set a transaction snapshot, so a write to a key committed by another transaction after this one began conflicts instead of silently overwriting it. - Remove the ReadCommitted isolation level: RocksDB could not reset the conflict snapshot per statement, so read committed allowed lost updates. TransactionIsolationLevel keeps RepeatableRead as the only level. - Remove docs/transaction-isolation.md and its RC-specific tests. --- README.md | 2 +- docs/features.md | 2 +- docs/transaction-isolation.md | 212 ---------------------------------- src/db.rs | 48 -------- src/docs.rs | 4 - src/lib.rs | 1 - src/storage/memory.rs | 4 - src/storage/mod.rs | 152 +----------------------- src/storage/rocksdb.rs | 131 ++++++++++----------- 9 files changed, 68 insertions(+), 488 deletions(-) delete mode 100644 docs/transaction-isolation.md delete mode 100644 src/docs.rs diff --git a/README.md b/README.md index 775f71c0..5e131801 100755 --- a/README.md +++ b/README.md @@ -95,7 +95,7 @@ More: [hello_world](examples/hello_world.rs), [transaction](examples/transaction | `build_in_memory()` | In-memory, for tests and temporary data | | `build_optimistic()` | RocksDB with optimistic transactions | -Feature flags, checkpoints, and transaction isolation: [docs/features.md](docs/features.md), [docs/transaction-isolation.md](docs/transaction-isolation.md). +Feature flags, checkpoints, and transaction isolation: [docs/features.md](docs/features.md). ## Shell, WebAssembly, Python diff --git a/docs/features.md b/docs/features.md index 40e64121..500b7e59 100644 --- a/docs/features.md +++ b/docs/features.md @@ -149,7 +149,7 @@ let kite_sql = DataBaseBuilder::path("./data") ### MVCC Transaction - Pessimistic (Default) - Optimistic -- Isolation levels: see [Transaction Isolation](transaction-isolation.md) +- Isolation level: repeatable read; every statement in a transaction reads the snapshot taken when it began ### Checkpoint KiteSQL exposes checkpoint as a storage capability rather than a full backup workflow.

That keeps "read your own writes" behavior intact while also -ensuring a statement or transaction uses one consistent committed view for -index scans and table lookups. - -### LMDB - -LMDB already provides a natural fixed snapshot view for a transaction, so -KiteSQL currently exposes only `RepeatableRead` there. - -KiteSQL intentionally does not emulate `ReadCommitted` on LMDB with extra -plumbing because that would complicate the storage contract and diverge from the -minimal implementation model used today. - -### Memory - -The in-memory storage currently exposes only `ReadCommitted`. - -This backend mainly exists for tests, examples, and temporary workloads, so the -implementation stays intentionally simple. - -## Conflict Detection in Current KiteSQL - -KiteSQL's current conflict detection is primarily key-based. - -In the RocksDB-backed implementation, table rows are stored under concrete KV -keys derived from the primary key, and write operations such as `INSERT`, -`UPDATE`, and `DELETE` ultimately modify those concrete keys through the storage -transaction. - -That means KiteSQL already has a solid baseline conflict detection capability -for cases like: - -- two transactions writing the same primary-key row -- two transactions rewriting the same concrete storage entry - -This is the most important transactional conflict detection foundation in the -current design: conflicts are naturally detected at the physical key level by -the underlying storage transaction mechanism. - -What KiteSQL does not currently provide is predicate-level or range-level -conflict detection such as: - -- "I read `a > 10`, so inserts into that range must now conflict" -- "I evaluated this SQL predicate, so future writes matching the predicate must - be blocked or rejected" - -Those stronger behaviors require explicit range locking, predicate locking, or -other higher-level concurrency control beyond today's key-based model. - -## Why This Matches RC and RR - -For ordinary SQL reads, the difference between `ReadCommitted` and -`RepeatableRead` is exactly the lifetime of the read snapshot: - -- `ReadCommitted`: snapshot lifetime is one statement -- `RepeatableRead`: snapshot lifetime is one transaction - -That is the rule KiteSQL enforces. - -As a result: - -- `ReadCommitted` prevents dirty reads because every statement reads from a - committed snapshot -- `ReadCommitted` allows non-repeatable reads across statements because a later - statement may use a newer snapshot -- `RepeatableRead` prevents non-repeatable reads because every statement uses - the same snapshot -- `RepeatableRead` also keeps repeated range reads stable because the visible - key space is evaluated against the same snapshot - -This is why KiteSQL's current key-level conflict detection is sufficient for -its present `ReadCommitted` and `RepeatableRead` support: - -- the basic write/write correctness still comes from the storage transaction's - concrete key conflict handling -- the `RC` / `RR` distinction itself comes from snapshot lifetime, not from - extra predicate conflict detection -- ordinary `RC` / `RR` reads do not require "I read this range, therefore other - transactions may not insert into it" semantics - -In other words, KiteSQL's current implementation satisfies the normal MVCC -definition of RC and RR for plain reads. - -## Scope and Non-Goals - -This document describes the guarantees for ordinary statement reads. - -It does not claim support for: - -- `Serializable` -- `SELECT ...

Scan iterators (tuple, index, table, view) live in arena-owned StorageIter slots and nodes keep an IterSlot, so ExecNode only borrows the plan and no longer carries T. - ExecArena::new takes the execution context and transaction; init_context and the Option-wrapped context are gone. - RecursiveCte's recursive arena is hosted by the outer arena, keeping the node free of transaction-bound state while reusing it across steps. - ExecNodes::push only appends; the overwrite path and seek are removed. --- src/db.rs | 10 +- src/db/prepared.rs | 40 ++- src/execution/ddl/add_column.rs | 4 +- src/execution/ddl/change_column.rs | 4 +- src/execution/ddl/create_index.rs | 4 +- src/execution/ddl/create_table.rs | 4 +- src/execution/ddl/create_view.rs | 4 +- src/execution/ddl/drop_column.rs | 4 +- src/execution/ddl/drop_index.rs | 4 +- src/execution/ddl/drop_table.rs | 4 +- src/execution/ddl/drop_view.rs | 4 +- src/execution/ddl/truncate.rs | 4 +- src/execution/dml/analyze.rs | 4 +- src/execution/dml/copy_from_file.rs | 4 +- src/execution/dml/copy_to_file.rs | 4 +- src/execution/dml/delete.rs | 4 +- src/execution/dml/insert.rs | 4 +- src/execution/dml/update.rs | 4 +- src/execution/dql/aggregate/hash_agg.rs | 6 +- src/execution/dql/aggregate/simple_agg.rs | 6 +- src/execution/dql/aggregate/stream_agg.rs | 6 +- .../dql/aggregate/stream_distinct.rs | 6 +- src/execution/dql/describe.rs | 6 +- src/execution/dql/dummy.rs | 6 +- src/execution/dql/explain.rs | 6 +- src/execution/dql/external_sort.rs | 6 +- src/execution/dql/filter.rs | 6 +- src/execution/dql/function_scan.rs | 6 +- src/execution/dql/index_scan.rs | 120 ++++--- src/execution/dql/join/hash_join.rs | 8 +- src/execution/dql/join/index_probe_join.rs | 9 +- src/execution/dql/join/nested_loop_join.rs | 11 +- src/execution/dql/limit.rs | 6 +- src/execution/dql/mark_apply.rs | 40 +-- src/execution/dql/projection.rs | 6 +- src/execution/dql/recursive_cte.rs | 63 ++-- src/execution/dql/scalar_query_init.rs | 13 +- src/execution/dql/scalar_subquery.rs | 6 +- src/execution/dql/seq_scan.rs | 84 ++--- src/execution/dql/set_membership.rs | 6 +- src/execution/dql/show_table.rs | 39 +-- src/execution/dql/show_view.rs | 39 +-- src/execution/dql/sort.rs | 9 +- src/execution/dql/top_k.rs | 6 +- src/execution/dql/union.rs | 6 +- src/execution/dql/values.rs | 6 +- src/execution/dql/window.rs | 6 +- src/execution/mod.rs | 319 +++++++++++------- 48 files changed, 537 insertions(+), 439 deletions(-) diff --git a/src/db.rs b/src/db.rs index 99f55756..d8bd98e6 100644 --- a/src/db.rs +++ b/src/db.rs @@ -762,8 +762,7 @@ impl State { let keeper = PlanKeeper::new(plan);

The arena-owned node array, ExecId, RefCell slots, the raw slot pointer and the executing counter are gone; ExecNode::next_tuple now clears the status, dispatches, and reports Continue/End as a bool. - MarkApply owns its right root; RightInput keeps only the scan state. NestedLoopJoin no longer copies the right input id into its states. - RecursiveCte builds each step into the outer arena and truncates the step's iterator slots afterwards, replacing the hosted sub-arena. The step's scans now carry the statement stamp like the rest of the tree. - Build no longer threads an execution context or transaction: ExecArena stores the table cache, the only catalog state executors read, and ExecutionContext plus LogicalPlan::exec_capacity_hint are removed. --- src/db.rs | 34 +- src/db/prepared.rs | 36 +- src/execution/ddl/add_column.rs | 12 +- src/execution/ddl/change_column.rs | 12 +- src/execution/ddl/create_index.rs | 19 +- src/execution/ddl/create_table.rs | 12 +- src/execution/ddl/create_view.rs | 12 +- src/execution/ddl/drop_column.rs | 12 +- src/execution/ddl/drop_index.rs | 12 +- src/execution/ddl/drop_table.rs | 12 +- src/execution/ddl/drop_view.rs | 12 +- src/execution/ddl/truncate.rs | 12 +- src/execution/dml/analyze.rs | 27 +- src/execution/dml/copy_from_file.rs | 20 +- src/execution/dml/copy_to_file.rs | 32 +- src/execution/dml/delete.rs | 24 +- src/execution/dml/insert.rs | 28 +- src/execution/dml/update.rs | 28 +- src/execution/dql/aggregate/hash_agg.rs | 24 +- src/execution/dql/aggregate/simple_agg.rs | 20 +- src/execution/dql/aggregate/stream_agg.rs | 30 +- .../dql/aggregate/stream_distinct.rs | 45 +-- src/execution/dql/describe.rs | 10 +- src/execution/dql/dummy.rs | 10 +- src/execution/dql/explain.rs | 12 +- src/execution/dql/external_sort.rs | 20 +- src/execution/dql/filter.rs | 26 +- src/execution/dql/function_scan.rs | 10 +- src/execution/dql/index_scan.rs | 23 +- src/execution/dql/join/hash_join.rs | 62 ++- src/execution/dql/join/index_probe_join.rs | 72 ++-- src/execution/dql/join/nested_loop_join.rs | 105 ++--- src/execution/dql/limit.rs | 26 +- src/execution/dql/mark_apply.rs | 302 ++++++-------- src/execution/dql/projection.rs | 18 +- src/execution/dql/recursive_cte.rs | 81 ++-- src/execution/dql/scalar_query_init.rs | 66 ++- src/execution/dql/scalar_subquery.rs | 26 +- src/execution/dql/seq_scan.rs | 20 +- src/execution/dql/set_membership.rs | 36 +- src/execution/dql/show_table.rs | 11 +- src/execution/dql/show_view.rs | 11 +- src/execution/dql/sort.rs | 56 +-- src/execution/dql/top_k.rs | 20 +- src/execution/dql/union.rs | 34 +- src/execution/dql/values.rs | 10 +- src/execution/dql/window.rs | 22 +- src/execution/mod.rs | 382 ++++-------------- src/planner/mod.rs | 22 +- 49 files changed, 654 insertions(+), 1314 deletions(-) diff --git a/src/db.rs b/src/db.rs index d8bd98e6..926fe2aa 100644 --- a/src/db.rs +++ b/src/db.rs @@ -19,7 +19,7 @@ pub use crate::binder::Statement;

It is built from the catalog at bind time and column pruning narrows it in place, so executors pass it straight to the storage reader instead of rebuilding deserializers on every execution. - storage: `read`/`read_by_index` take `&TupleDeserializers`; the column-based wrappers and `create_deserializers` are removed. - scans returning primary keys keep their primary key columns read. - `index_covering`, `is_index_covers` and `fmt_explain_list` accept iterators; `index_covering` resolves coverage in a single pass. - the persisted view plan format changes with TableScanOperator. --- src/db/prepared.rs | 2 +- src/execution/dql/index_scan.rs | 10 +- src/execution/dql/seq_scan.rs | 13 +- src/optimizer/plan_utils.rs | 7 +- .../rule/implementation/dql/filter.rs | 2 +- .../rule/normalization/column_pruning.rs | 20 +- .../rule/normalization/elimination.rs | 13 +- .../rule/normalization/join_reorder.rs | 2 +- .../rule/normalization/parameterized_index.rs | 28 +- .../rule/normalization/pushdown_predicates.rs | 61 ++-- src/planner/mod.rs | 18 +- src/planner/operator/mod.rs | 6 +- src/planner/operator/table_scan.rs | 17 +- src/planner/operator/visitor.rs | 2 +- src/storage/memory.rs | 48 ++- src/storage/mod.rs | 322 +++++++++++------- src/storage/rocksdb.rs | 113 +++--- 17 files changed, 401 insertions(+), 283 deletions(-) diff --git a/src/db/prepared.rs b/src/db/prepared.rs index adba18de..d4e2e0dd 100644 --- a/src/db/prepared.rs +++ b/src/db/prepared.rs @@ -299,7 +299,7 @@ mod tests { let mut scan = LogicalPlan::new( Operator::TableScan(TableScanOperator { table_name: "t".into(), - columns: vec![column], + deserializers: crate::storage::deserializers_for_test(vec![column]), limit: (None, None), index_infos: vec![index.clone(), other.clone()], with_pk: false, diff --git a/src/execution/dql/index_scan.rs b/src/execution/dql/index_scan.rs index 1bc6b539..2d227a34 100644 --- a/src/execution/dql/index_scan.rs +++ b/src/execution/dql/index_scan.rs @@ -133,7 +133,7 @@ impl<'a, T: StorageTransaction + 'a> ExecutorNode<'a, T> for IndexScan<'a> { let ranges = Self::ranges(self.info, self.lookup, arena, plan_arena)?;

A finished iterator hands it back with `into_executor`, reset and ready to run again, possibly in another transaction: let exec = tx1.execute(&prepared, params)?.into_executor()?; tx1.commit()?; let iter = tx2.execute(exec, other_params)?; - `Database::execute` and `Transaction::execute` take `impl IntoExecutor`, implemented for prepared plans and executors. - `TransactionIter` gains a plan lifetime `'p`, separate from the transaction borrow, so a returned executor outlives the transaction. - Building a tree no longer needs a transaction: build functions take an `ExecBuilder`, which counts slots ahead of execution or allocates them in the arena while a recursive CTE runs. - `ExecutorNode::reset` is required; write nodes keep their input and track whether they ran instead of taking it. - `BindSource::execute` builds return an executor; `Executor::from_plan` covers the SQL paths. --- src/binder/parser.rs | 30 +- src/db.rs | 286 ++++++++++++------ src/db/prepared.rs | 42 +-- src/execution/ddl/add_column.rs | 18 +- src/execution/ddl/change_column.rs | 18 +- src/execution/ddl/create_index.rs | 20 +- src/execution/ddl/create_table.rs | 18 +- src/execution/ddl/create_view.rs | 18 +- src/execution/ddl/drop_column.rs | 18 +- src/execution/ddl/drop_index.rs | 18 +- src/execution/ddl/drop_table.rs | 18 +- src/execution/ddl/drop_view.rs | 18 +- src/execution/ddl/truncate.rs | 18 +- src/execution/dml/analyze.rs | 34 ++- src/execution/dml/copy_from_file.rs | 18 +- src/execution/dml/copy_to_file.rs | 33 +- src/execution/dml/delete.rs | 37 ++- src/execution/dml/insert.rs | 32 +- src/execution/dml/update.rs | 32 +- src/execution/dql/aggregate/hash_agg.rs | 10 +- src/execution/dql/aggregate/simple_agg.rs | 10 +- src/execution/dql/aggregate/stream_agg.rs | 10 +- .../dql/aggregate/stream_distinct.rs | 10 +- src/execution/dql/describe.rs | 10 +- src/execution/dql/dummy.rs | 10 +- src/execution/dql/explain.rs | 10 +- src/execution/dql/external_sort.rs | 10 +- src/execution/dql/filter.rs | 10 +- src/execution/dql/function_scan.rs | 10 +- src/execution/dql/index_scan.rs | 12 +- src/execution/dql/join/hash_join.rs | 10 +- src/execution/dql/join/index_probe_join.rs | 14 +- src/execution/dql/join/nested_loop_join.rs | 12 +- src/execution/dql/limit.rs | 10 +- src/execution/dql/mark_apply.rs | 34 +-- src/execution/dql/projection.rs | 10 +- src/execution/dql/recursive_cte.rs | 18 +- src/execution/dql/scalar_query_init.rs | 20 +- src/execution/dql/scalar_subquery.rs | 10 +- src/execution/dql/seq_scan.rs | 12 +- src/execution/dql/set_membership.rs | 10 +- src/execution/dql/show_table.rs | 12 +- src/execution/dql/show_view.rs | 12 +- src/execution/dql/sort.rs | 13 +- src/execution/dql/top_k.rs | 10 +- src/execution/dql/union.rs | 10 +- src/execution/dql/values.rs | 10 +- src/execution/dql/window.rs | 10 +- src/execution/mod.rs | 212 ++++++++----- src/orm/dql.rs | 22 +- src/orm/mod.rs | 28 +- src/planner/plan_keeper.rs | 14 +- 52 files changed, 825 insertions(+), 526 deletions(-) diff --git a/src/binder/parser.rs b/src/binder/parser.rs index b684c7b3..70e759f8 100644 --- a/src/binder/parser.rs +++ b/src/binder/parser.rs @@ -21,7 +21,9 @@ use super::{is_valid_identifier, Binder, CteBinding, QueryBindStep, SetOperatorK #[cfg(feature = "copy")] use crate::binder::copy::{ExtSource, FileFormat};

Each execution binds new parameters and reuses the tree instead of rebuilding it, in any transaction of the database that created it. - `Database::program_sql` / `Transaction::program_sql` and the ORM `program` replace `prepare_sql` / `prepare`. - `Program::execute(&mut tx, params)` returns a `ProgramIter`, which puts the program back when the execution ends, even if it fails. - Remove `PreparedPlan`, `Database::execute` and `Transaction::execute`; prepared statements now run inside a transaction. - `ParamArena` owns its plan arena, and `PlanInput` is gone since plans are no longer borrowed. - TPCC keeps one program per statement; add the `program` example. --- Makefile | 1 + README.md | 2 +- examples/program.rs | 102 +++++++++ src/binder/parser.rs | 26 ++- src/db.rs | 310 +++++++++++++--------------- src/db/{prepared.rs => program.rs} | 302 +++++++++++++++++++++------ src/execution/mod.rs | 22 +- src/orm/README.md | 20 +- src/orm/dql.rs | 15 +- src/orm/mod.rs | 57 ++--- src/planner/arena.rs | 108 +++++----- src/planner/mod.rs | 2 +- src/planner/plan_keeper.rs | 53 +---- src/storage/lmdb.rs | 12 +- tpcc/src/backend/dual.rs | 8 +- tpcc/src/backend/kitesql_lmdb.rs | 8 +- tpcc/src/backend/kitesql_rocksdb.rs | 18 +- tpcc/src/backend/mod.rs | 4 +- 18 files changed, 662 insertions(+), 408 deletions(-) create mode 100644 examples/program.rs rename src/db/{prepared.rs => program.rs} (69%) diff --git a/Makefile b/Makefile index 9184ba38..5056f3aa 100644 --- a/Makefile +++ b/Makefile @@ -169,3 +169,4 @@ wasm-examples: native-examples: $(CARGO) run --example hello_world $(CARGO) run --example transaction + $(CARGO) run --example program diff --git a/README.md b/README.md index 5e131801..76b12a10 100755 --- a/README.md +++ b/README.md @@ -85,7 +85,7 @@ fn main() -> Result<(), DatabaseError> { } ``` -More: [hello_world](examples/hello_world.rs), [transaction](examples/transaction.rs). +More: [hello_world](examples/hello_world.rs), [transaction](examples/transaction.rs), [program](examples/program.rs). ## Storage Backends | Builder | Storage | diff --git a/examples/program.rs b/examples/program.rs new file mode 100644 index 00000000..0fe13fa6 --- /dev/null +++ b/examples/program.rs @@ -0,0 +1,102 @@ +// Copyright 2024 KipData/KiteSQL +// +// Licensed under the Apache License, Version 2.0 (the "License"); +// you may not use this file except in compliance with the License. +// You may obtain a copy of the License at +// +// http://www.apache.org/licenses/LICENSE-2.0 +// +// Unless required by applicable law or agreed to in writing, software +// distributed under the License is distributed on an "AS IS" BASIS, +// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +// See the License for the specific language governing permissions and +// limitations under the License. + +#[cfg(not(target_arch = "wasm32"))] +mod app { + use kite_sql::db::DataBaseBuilder; + use kite_sql::errors::DatabaseError; + use kite_sql::types::value::DataValue; + use kite_sql::types::LogicalType; + use std::fs; + use std::io::ErrorKind; + use std::path::Path; + + const EXAMPLE_DB_PATH: &str = "./example_data/program"; + + fn reset_example_dir() -> Result<(), DatabaseError> { + if let Err(err) = fs::remove_dir_all(EXAMPLE_DB_PATH) { + if err.kind() != ErrorKind::NotFound { + return Err(err.into()); + } + } + + if let Some(parent) = Path::new(EXAMPLE_DB_PATH).parent() { + fs::create_dir_all(parent)?; + } + + Ok(()) + } + + pub fn run() -> Result<(), DatabaseError> { + reset_example_dir()?; + let mut database = DataBaseBuilder::path(EXAMPLE_DB_PATH).build_rocksdb()?; + database.ddl("create table t1 (c1 int primary key, c2 int)")?; + database + .run("insert into t1 values(0, 0), (1, 1), (2, 2)")? + .done()?; + + // A program is parsed, optimized and built into executors once.

`BindSource` returns `DatabaseError` again, with a `PlanArena` instead of a boxed arena. - Remove the unsafe move out and write back (`ptr::read`/`ptr::write`, `AbortOnUnwind`, `ManuallyDrop`) and `TransactionIter::into_program`. - Split `begin_execution` out of `start_execution` to start an executor in place; `TransactionGuard::next_tuple` serves both iterators. - `ParamArena::bind` overwrites the bound values in place instead of rebuilding every parameter expression. --- examples/program.rs | 4 +- src/binder/parser.rs | 14 +-- src/db.rs | 237 +++++++++++++++---------------------------- src/db/program.rs | 162 ++++++++--------------------- src/orm/mod.rs | 41 ++++---- src/planner/arena.rs | 35 ++++++- 6 files changed, 184 insertions(+), 309 deletions(-) diff --git a/examples/program.rs b/examples/program.rs index 0fe13fa6..80ccb0e8 100644 --- a/examples/program.rs +++ b/examples/program.rs @@ -48,8 +48,8 @@ mod app { // A program is parsed, optimized and built into executors once.

`is_mapping_by_name` is gone. - `UpdateOperator.value_exprs` holds table positions. Every assignment reads the old row, and assigning a column twice is rejected. - `get_column_by_id` returns the column position too, which removes the linear scans that looked it up again. - Add `TupleImpl::clear`; Insert reuses one tuple for its rows. --- src/binder/insert.rs | 77 ++++++- src/binder/parser.rs | 51 ++--- src/binder/select.rs | 39 ++-- src/binder/update.rs | 42 +++- src/catalog/table.rs | 74 ++++--- src/execution/dml/insert.rs | 152 +++++-------- src/execution/dml/update.rs | 203 ++++++------------ .../normalization/compilation_in_advance.rs | 3 +- src/orm/mod.rs | 44 +--- src/planner/operator/insert.rs | 7 +- src/planner/operator/mod.rs | 13 +- src/planner/operator/table_scan.rs | 2 +- src/planner/operator/update.rs | 9 +- src/planner/operator/visitor.rs | 5 +- src/serdes/column.rs | 2 +- src/storage/mod.rs | 4 +- src/types/index.rs | 6 +- src/types/tuple.rs | 5 + 18 files changed, 358 insertions(+), 380 deletions(-) diff --git a/src/binder/insert.rs b/src/binder/insert.rs index 0778edb1..196caa0a 100644 --- a/src/binder/insert.rs +++ b/src/binder/insert.rs @@ -13,33 +13,57 @@ // limitations under the License. use crate::binder::Binder;

Nodes get both through `ExecContext`. - `ExecBuffer::reset` drops what an unfinished execution left behind. - Size the key buffers once with `DataValue::memcomparable_len_hint`, and the tuple and index values with their length hints plus the stamp. --- src/db.rs | 4 +- src/db/program.rs | 10 +- src/execution/ddl/add_column.rs | 6 +- src/execution/ddl/change_column.rs | 6 +- src/execution/ddl/create_index.rs | 6 +- src/execution/ddl/create_table.rs | 6 +- src/execution/ddl/create_view.rs | 6 +- src/execution/ddl/drop_column.rs | 6 +- src/execution/ddl/drop_index.rs | 6 +- src/execution/ddl/drop_table.rs | 6 +- src/execution/ddl/drop_view.rs | 6 +- src/execution/ddl/truncate.rs | 6 +- src/execution/dml/analyze.rs | 6 +- src/execution/dml/copy_from_file.rs | 6 +- src/execution/dml/copy_to_file.rs | 8 +- src/execution/dml/delete.rs | 8 +- src/execution/dml/insert.rs | 8 +- src/execution/dml/update.rs | 8 +- src/execution/dql/aggregate/hash_agg.rs | 8 +- src/execution/dql/aggregate/simple_agg.rs | 8 +- src/execution/dql/aggregate/stream_agg.rs | 8 +- .../dql/aggregate/stream_distinct.rs | 8 +- src/execution/dql/describe.rs | 6 +- src/execution/dql/dummy.rs | 6 +- src/execution/dql/explain.rs | 6 +- src/execution/dql/external_sort.rs | 8 +- src/execution/dql/filter.rs | 8 +- src/execution/dql/function_scan.rs | 6 +- src/execution/dql/index_scan.rs | 22 ++- src/execution/dql/join/hash_join.rs | 10 +- src/execution/dql/join/index_probe_join.rs | 16 +- src/execution/dql/join/nested_loop_join.rs | 12 +- src/execution/dql/limit.rs | 8 +- src/execution/dql/mark_apply.rs | 47 +++-- src/execution/dql/projection.rs | 8 +- src/execution/dql/recursive_cte.rs | 14 +- src/execution/dql/scalar_query_init.rs | 14 +- src/execution/dql/scalar_subquery.rs | 8 +- src/execution/dql/seq_scan.rs | 19 +- src/execution/dql/set_membership.rs | 8 +- src/execution/dql/show_table.rs | 6 +- src/execution/dql/show_view.rs | 6 +- src/execution/dql/sort.rs | 14 +- src/execution/dql/top_k.rs | 8 +- src/execution/dql/union.rs | 8 +- src/execution/dql/values.rs | 6 +- src/execution/dql/window.rs | 8 +- src/execution/mod.rs | 186 +++++++++++------- src/storage/mod.rs | 2 +- src/storage/table_codec.rs | 25 ++- src/types/tuple.rs | 22 ++- src/types/value.rs | 14 ++ 52 files changed, 429 insertions(+), 252 deletions(-) diff --git a/src/db.rs b/src/db.rs index fe9a246e..34683373 100644 --- a/src/db.rs +++ b/src/db.rs @@ -627,7 +627,7 @@ fn begin_execution<'a, 'p, T: StorageTransaction + 'p, A: MetaArena + 'p>( ) -> Result, DatabaseError> { let stamp = statement_stamp(transaction, executor.plan())?;

planning, execution and serialization work with table ids, and names only come back for display. - The table arena owns the catalog: `NameMapping`, `TableCache` keyed by `TableId` and `ViewCache`. `MetaArena::table(id)` looks a table up, and `table_name` derives from it, replacing the separate name registry. - `ColumnRelation` splits into `Table { table_id, column_id }` and `Source { source_id, column_id, is_temp }`. Other FROM items only carry an id; the source name list is gone and explain shows them as `#id.column`. - The binder matches columns to sources by relation instead of names, and `BoundSource` borrows its name from the catalog. - Drop `table_aliases`: a FROM item names a real table, not an earlier alias. `with_pk` holds a table id. - Scans, DML and DDL operators carry the table id; DDL executors take the name from the cached catalog, and binder and storage entry points take `&str` instead of owned names. - Column ref decoding finds catalog columns through the arena, so the decode context no longer holds a transaction. --- .../src/reference_serialization.rs | 16 +- src/bin/shell.rs | 2 +- src/binder/aggregate.rs | 6 +- src/binder/alter_table.rs | 14 +- src/binder/analyze.rs | 9 +- src/binder/copy.rs | 11 +- src/binder/create_index.rs | 14 +- src/binder/create_table.rs | 4 +- src/binder/create_view.rs | 17 +- src/binder/delete.rs | 11 +- src/binder/describe.rs | 10 +- src/binder/expr.rs | 2 +- src/binder/insert.rs | 16 +- src/binder/mod.rs | 198 ++--- src/binder/parser.rs | 136 ++-- src/binder/select.rs | 147 ++-- src/binder/truncate.rs | 13 +- src/binder/update.rs | 12 +- src/catalog/column.rs | 80 +- src/catalog/table.rs | 17 +- src/catalog/view.rs | 2 +- src/db.rs | 141 ++-- src/db/program.rs | 10 +- src/execution/ddl/add_column.rs | 18 +- src/execution/ddl/change_column.rs | 23 +- src/execution/ddl/create_index.rs | 16 +- src/execution/ddl/create_view.rs | 4 +- src/execution/ddl/drop_column.rs | 22 +- src/execution/ddl/drop_index.rs | 14 +- src/execution/ddl/truncate.rs | 8 +- src/execution/ddl_apply.rs | 13 +- src/execution/dml/analyze.rs | 132 +-- src/execution/dml/copy_from_file.rs | 13 +- src/execution/dml/copy_to_file.rs | 7 +- src/execution/dml/delete.rs | 20 +- src/execution/dml/insert.rs | 1 - src/execution/dml/update.rs | 9 +- src/execution/dql/describe.rs | 10 +- src/execution/dql/index_scan.rs | 12 +- src/execution/dql/join/nested_loop_join.rs | 4 +- src/execution/dql/seq_scan.rs | 24 +- src/execution/mod.rs | 6 - src/expression/mod.rs | 134 ++-- src/expression/range_detacher.rs | 750 +++++++++++------- src/optimizer/core/cm_sketch.rs | 40 +- src/optimizer/core/histogram.rs | 2 +- src/optimizer/core/statistics_meta.rs | 31 +- src/optimizer/heuristic/optimizer.rs | 3 +- src/optimizer/plan_utils.rs | 27 +- .../rule/implementation/dql/filter.rs | 6 +- .../rule/implementation/dql/table_scan.rs | 4 +- .../rule/normalization/column_pruning.rs | 2 +- .../normalization/compilation_in_advance.rs | 1 - .../normalization/constant_propagation.rs | 2 +- .../rule/normalization/elimination.rs | 17 +- .../rule/normalization/join_reorder.rs | 49 +- .../rule/normalization/parameterized_index.rs | 23 +- .../rule/normalization/pushdown_predicates.rs | 58 +- .../rule/normalization/simplification.rs | 24 +- src/orm/ddl.rs | 12 +- src/orm/dql.rs | 4 +- src/orm/mod.rs | 46 +- src/planner/arena.rs | 78 +- src/planner/mod.rs | 108 ++- .../operator/alter_table/add_column.rs | 27 +- .../operator/alter_table/change_column.rs | 14 +- .../operator/alter_table/drop_column.rs | 25 +- src/planner/operator/analyze.rs | 10 +- src/planner/operator/copy_from_file.rs | 10 +- src/planner/operator/create_index.rs | 10 +- src/planner/operator/delete.rs | 20 +- src/planner/operator/describe.rs | 20 +- src/planner/operator/insert.rs | 23 +- src/planner/operator/mod.rs | 77 +- src/planner/operator/table_scan.rs | 13 +- src/planner/operator/truncate.rs | 21 +- src/planner/operator/update.rs | 8 +- src/planner/operator/visitor.rs | 26 +- src/planner/operator/window.rs | 6 +- src/planner/scalar_query_ref.rs | 34 +- src/serdes/boolean.rs | 10 +- src/serdes/bound.rs | 14 +- src/serdes/btree_map.rs | 20 +- src/serdes/char.rs | 6 +- src/serdes/char_length_units.rs | 29 +- src/serdes/column.rs | 141 ++-- src/serdes/data_value.rs | 55 +- src/serdes/evaluator.rs | 205 ++--- src/serdes/expression.rs | 12 +- src/serdes/function.rs | 51 +- src/serdes/hasher.rs | 14 +- src/serdes/index.rs | 12 +- src/serdes/mod.rs | 143 +--- src/serdes/num.rs | 86 +- src/serdes/option.rs | 16 +- src/serdes/pair.rs | 14 +- src/serdes/path_buf.rs | 15 +- src/serdes/phantom.rs | 6 +- src/serdes/physical_option.rs | 56 +- src/serdes/ptr.rs | 12 +- src/serdes/slice.rs | 14 +- src/serdes/string.rs | 32 +- src/serdes/trim.rs | 6 +- src/serdes/vec.rs | 16 +- src/storage/lmdb.rs | 6 +- src/storage/memory.rs | 60 +- src/storage/mod.rs | 391 +++++---- src/storage/rocksdb.rs | 108 ++- src/storage/table_codec.rs | 255 ++---- src/types/evaluator/binary.rs | 12 +- src/types/evaluator/cast.rs | 12 +- src/types/evaluator/unary.rs | 12 +- src/types/index.rs | 15 +- src/types/mod.rs | 126 +-- src/types/tuple.rs | 4 + 115 files changed, 2381 insertions(+), 2614 deletions(-) diff --git a/kite_sql_serde_macros/src/reference_serialization.rs b/kite_sql_serde_macros/src/reference_serialization.rs index 8cc7b38d..1c018866 100644 --- a/kite_sql_serde_macros/src/reference_serialization.rs +++ b/kite_sql_serde_macros/src/reference_serialization.rs @@ -117,10 +117,10 @@ pub(crate) fn handle(ast: DeriveInput) -> Result { let ty = process_type(&field_opts.ty);

Decoding takes from it, and the row buffer gives its old values back before the next decode. It holds at most 64 buffers of up to 4096 bytes. - Char, Varchar and Varbinary decode from the input slice instead of a zeroed vector; CHAR trims the padding before copying. - `TupleValueSerializable::filling_value` takes the pool and is the only decode method; `from_raw` is gone. - `with_tuple_bound` and `with_tuple_unchecked` hand the pool to their closure, since the codec stays borrowed while it runs. - `rewrite` evaluates into a spare vector and swaps it with the row, instead of appending and rotating; borrowed values are copied through the pool. - Primary key lookups clone the tuple id only when they hit and keep it. --- src/execution/ddl/mod.rs | 5 +- src/execution/mod.rs | 45 ++--- src/storage/mod.rs | 59 +++--- src/storage/table_codec.rs | 78 +++++--- src/types/serialize.rs | 381 ++++++++++++++++++++++++------------- src/types/tuple.rs | 51 ++++- 6 files changed, 387 insertions(+), 232 deletions(-) diff --git a/src/execution/ddl/mod.rs b/src/execution/ddl/mod.rs index 081629f1..716b44e3 100644 --- a/src/execution/ddl/mod.rs +++ b/src/execution/ddl/mod.rs @@ -52,14 +52,14 @@ where I: IntoIterator, { let lower = if let Some(last_pk) = start_after { - table_codec.with_tuple_unchecked(table_id, last_pk, None, |key, _| { + table_codec.with_tuple_unchecked(table_id, last_pk, None, |key, _, _| { Ok::<_, DatabaseError>(Bound::Excluded(key.to_vec())) })?

expectations after the table id refactor - tpcc: `explain_tpcc` names columns through `SchemaView::full_name`. - macros-test: drop `UserOrderSummary`, unused since the ORM refactor. - db: `test_prepare_statment` expects derived table columns as `#id.column`. - slt: explain plans match source ids with ``, since the ids depend on the views loaded before; `show views` lists views by id.
