longvu-db opened a new pull request, #57043:
URL: https://github.com/apache/spark/pull/57043
### What changes were proposed in this pull request?
Spark Connect re-resolves and re-analyzes each plan on every request, so by
the time a plan reaches execution the analyzed plan already references the
latest table state. The `QueryExecution` refresh phase
(`tableVersionsRefreshed`, backed by `V2TableRefreshUtil.refresh`) then reloads
every versioned DSv2 relation from the catalog again, issuing redundant
`catalog.loadTable` calls for tables that were just resolved in the same
`QueryExecution`.
This change disables the refresh phase on the Spark Connect server-side
execution and analysis paths by threading `refreshPhaseEnabled = false` through
the `QueryExecution` construction sites Connect uses.
Details:
- Add a `refreshPhaseEnabled` parameter to `SessionState.executePlan`,
forwarded through the `createQueryExecution` factory
(`BaseSessionStateBuilder`, and the `TestHive` override). Defaults preserve
classic behavior.
- Add a `Dataset.ofRows` overload that accepts `refreshPhaseEnabled`, and
thread the flag through the tracker-taking overload. Only one overload may
define default arguments, so the new plan-only overload takes the flag without
a default.
- Pass `refreshPhaseEnabled = false` at all Spark Connect server-side
`QueryExecution` / `Dataset.ofRows` / `executePlan` sites
(`SparkConnectPlanExecution`, `SparkConnectAnalyzeHandler`,
`SparkConnectPlanner`, `MLUtils`).
### Why are the changes needed?
To avoid extra catalog round-trips in Spark Connect that do not change the
outcome. In Connect, analysis and execution happen together, so the refresh
phase is redundant. The refresh phase is not what keeps stored-plan temp views
fresh (that is the `V2TableReference` analyzer rule), so disabling it does not
regress view or table freshness.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Existing DSv2 freshness suites pass unchanged:
- `DataSourceV2DataFrameConnectSuite` (49 tests) verifies that repeated
`sql()`/`table()` access, temp views with stored plans, incrementally
constructed joins, and CACHE TABLE all still reflect session and external
mutations with the refresh phase disabled.
- `DataSourceV2DataFrameSuite` (203 tests, classic) confirms classic
behavior is unchanged.
- `QueryExecutionSuite` (27 tests) confirms the widened `ofRows` /
`executePlan` defaults are preserved.
