From 4c3ce8d1701624a0dd20fd176659b7274cdcfbd8 Mon Sep 17 00:00:00 2001 From: Sandeep Gottimukkala Date: Sat, 4 Apr 2026 22:57:10 -0700 Subject: [PATCH 1/9] feat(rest): add scan plan endpoints to REST catalog client - Add PlanTableScan, FetchPlanningResult, CancelPlanning, FetchScanTasks methods to RestCatalog, wiring them to the corresponding REST endpoints - Add scan plan endpoint definitions and resource path helpers - Add ScanPlanErrorHandler with proper 404/406 error dispatch (NoSuchPlanIdException, NoSuchPlanTaskException, etc.) - Add PlanTableScanRequest/FetchScanTasksRequest serialization helpers - Add kNoSuchPlanId and kNoSuchPlanTask ErrorKind values - Add DataFileFromJson and FileScanTasksFromJson overloads with partition spec and schema support - Add endpoint and integration tests for all 4 scan plan operations --- src/iceberg/catalog.h | 18 ++ src/iceberg/catalog/rest/endpoint.h | 17 ++ src/iceberg/catalog/rest/error_handlers.cc | 33 +++ src/iceberg/catalog/rest/error_handlers.h | 10 + src/iceberg/catalog/rest/json_serde.cc | 125 +++++++++ .../catalog/rest/json_serde_internal.h | 22 ++ src/iceberg/catalog/rest/resource_paths.cc | 21 ++ src/iceberg/catalog/rest/resource_paths.h | 4 + src/iceberg/catalog/rest/rest_catalog.cc | 81 ++++++ src/iceberg/catalog/rest/rest_catalog.h | 8 + src/iceberg/catalog/rest/types.cc | 81 ++++++ src/iceberg/catalog/rest/types.h | 63 +++++ src/iceberg/json_serde.cc | 252 ++++++++++++++++++ src/iceberg/json_serde_internal.h | 35 +++ src/iceberg/result.h | 4 + src/iceberg/table_scan.h | 41 +++ src/iceberg/test/endpoint_test.cc | 33 ++- src/iceberg/test/json_serde_test.cc | 229 ++++++++++++++++ .../test/rest_catalog_integration_test.cc | 90 +++++++ 19 files changed, 1164 insertions(+), 3 deletions(-) diff --git a/src/iceberg/catalog.h b/src/iceberg/catalog.h index 81c9ddd11..c1f2530ea 100644 --- a/src/iceberg/catalog.h +++ b/src/iceberg/catalog.h @@ -26,8 +26,10 @@ #include #include +#include "iceberg/catalog/rest/types.h" #include "iceberg/result.h" #include "iceberg/table_identifier.h" +#include "iceberg/table_scan.h" #include "iceberg/type_fwd.h" namespace iceberg { @@ -188,6 +190,22 @@ class ICEBERG_EXPORT Catalog { /// \return a Table instance or ErrorKind::kAlreadyExists if the table already exists virtual Result> RegisterTable( const TableIdentifier& identifier, const std::string& metadata_file_location) = 0;
