Problem Summary:

Release note

Implement a global monotonically increasing Timestamp Oracle (TSO) service that generates unique, monotonically increasing timestamps for transactions.
The service calibrates its initial timestamp at startup and periodically updates it to maintain a time window.
A TSO timestamp encodes the physical time and a logical counter; it is assembled and extracted by the new TSOTimestamp class.
Introduce TSOService, a master-only daemon that manages global timestamps.
The service exposes two main methods:
- getTSO() – returns a new TSO timestamp for transaction commits.
- getCurrentTSO() – returns the current TSO without bumping the logical counter.
Add multiple configuration properties to control the behavior of the TSO feature:
- experimental_enable_feature_tso – enables/disables the TSO feature.
- tso_service_update_interval_ms – interval in milliseconds for the TSO service to update its window.
- max_update_tso_retry_count and max_get_tso_retry_count – retry limits for updating and obtaining TSOs.
- tso_service_window_duration_ms – length of the time window allocated by the TSO service.
- tso_time_offset_debug_mode – debug offset for the physical time.
- enable_tso_persist_journal and enable_tso_checkpoint_module – persistence switches for edit log and checkpoint.
Table property: Introduce enable_tso which can be configured in CREATE TABLE or modified via ALTER TABLE. Only tables with enable_tso = true generate commit TSO for transactions; when disabled, commit_tso remains -1.
Transaction and commit integration:
- During commit, TransactionState now fetches a commit TSO from TSOService when TSO is enabled and stores it in the transaction state and TableCommitInfo.
- The commit TSO is recorded per partition (via TPartitionVersionInfo.commit_tso), and is persisted with each rowset (see next item).
Rowset and meta changes:
- Rowset::make_visible now accepts a commit_tso parameter and writes it to RowsetMeta.
- RowsetMetaPB adds a new field commit_tso to persist commit timestamps.
- information_schema.rowsets introduces a new column COMMIT_TSO allowing users to query the commit timestamp for each rowset.
- Pending publish tasks, asynchronous publish tasks and other internal structures have been extended to carry commit TSO.
External interface:
A new REST endpoint /api/tso is added for retrieving current TSO information. It returns a JSON payload containing:
- window_end_physical_time – end of the current TSO time window.
- current_tso – the current composed 64‑bit TSO.
- current_tso_physical_time and current_tso_logical_counter – the decomposed physical and logical parts of the current TSO. This API does not increment the logical counter.
Metrics & observability:
New metrics counters (e.g., tso_clock_drift_detected, tso_clock_backward_detected, tso_clock_calculated, tso_clock_updated) expose state and health of the TSO service.
Regression & unit tests:
New unit tests verify TSOTimestamp bit manipulation, TSOService behavior, commit TSO propagation, and the /api/tso endpoint. Regression tests verify that rowset commit timestamps are populated when TSO is enabled and that the API returns increasing TSOs.

Impact and Compatibility

Experimental: the TSO feature is currently guarded by experimental_enable_feature_tso. It is disabled by default and can be enabled in front-end configuration. When enabled, old FE versions without this feature cannot replay edit log entries containing TSO operations; therefore upgrade all FEs before enabling.
Table compatibility: tables created before enabling TSO remain unaffected unless explicitly modified to set enable_tso to true. Tables with TSO enabled will produce commit TSO for each rowset and may require downstream consumers to handle the new commit_tso field.
Client API: clients can call /api/tso to inspect current TSO values. No existing API is modified.

Test Coverage Analysis

The core TSO logic (TSOTimestamp + TSOService) has solid unit test coverage. However, the integration seams — where TSO meets the transaction commit path, DDL operations, BE publish pipeline, and edit log replay — are under-tested.

What's Well Covered

TSOTimestamp — 11 test methods: constructor, compose/extract, bit-width masking, negative validation, serialization round-trip, compareTo, MAX_LOGICAL_COUNTER.
TSOService — ~20 tests: getTSO error paths, runAfterCatalogReady, calibrateTimestamp (persist failure, clock backward, journal disabled, fatal flag reset), updateTimestamp, generateTSO, writeTimestampToBDBJE, save/load round-trip.
Commit TSO in transactions — TSO set when enableTso=true, remains -1 when enableTso=false.
Regression tests — REST API validation (monotonicity, composition) and end-to-end COMMIT_TSO in information_schema.rowsets.

Gaps

High Priority:

No concurrent getTSO() test — TSOService uses ReentrantLock + AtomicLong, but no test verifies correctness under concurrent access. For a globally-monotonic TSO, this is critical.
getCommitTSO() error paths untested — DatabaseTransactionMgr.getCommitTSO() has 5 branches but only 2 tested. Missing:
- Config.enable_tso_feature = false (global disable)
- TSOService throws exception during commit → TransactionCommitFailedException
- TSOService returns <= 0
- Mixed tables (some TSO-enabled, some not)
No ALTER TABLE ... SET ("enable_tso" = "true/false") test — ModifyTablePropertiesOp (+16 lines) and PropertyAnalyzer (+23 lines) have zero test coverage. Regression tests only cover CREATE TABLE.

Medium Priority:

TSOAction.java has no unit test — Error paths (FE not ready, non-master FE, exception) untested. Only happy path via regression.
BE C++ plumbing largely untested — Changes span 10+ files propagating commit_tso. Specific gaps:
- pb_convert.cpp — 4 new has_commit_tso() blocks, no test
- schema_rowsets_scanner.cpp — COMMIT_TSO column fill, no BE unit test
- DiscontinuousVersionTablet struct, no test
- engine_publish_version_task.cpp — significant refactoring, no direct test
Edit log replay path — replayWindowEndTSO is tested, but the full path (deserialize from journal → dispatch via OP_TSO_TIMESTAMP_WINDOW_END → replay) is not.
Metrics — 4 new counters (tso_clock_drift_detected, tso_clock_backward_detected, tso_clock_calculated, tso_clock_updated) never asserted in any test.

Low Priority:

No regression test for TSO-disabled tables (verifying commit_tso stays -1).
SchemaChangeHandler / CloudSchemaChangeHandler enable_tso validation — no test.
No integration test for TSO state surviving FE restart/checkpoint recovery.

…riptions to ensure clarity of the descriptive information.

…er is nearly full
