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 ... FOR UPDATE` -- explicit row-lock or range-lock APIs -- lock-based writer scheduling semantics beyond what the underlying storage - already provides - -Those features can be added later without changing the core visibility model -used here for `ReadCommitted` and `RepeatableRead`. diff --git a/examples/program.rs b/examples/program.rs new file mode 100644 index 00000000..80ccb0e8 --- /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.
