DeltaCommitFileProvider¶

deltaFile¶

deltaFile(
  version: Long): Path

deltaFile looks up the given version (in the uuids registry).

When found, deltaFile creates an unbackfilledDeltaFile for this resolvedPath, the given version and the found uuid.

Otherwise, deltaFile creates a unsafeDeltaFile for this resolvedPath and the given version.

Cannot resolve Delta table at version [version] as the state is currently at version [maxVersionInclusive].
The requested version may be incorrect or the state may be outdated.
Please verify the requested version, update the state if necessary, and try again

deltaFile is used when:

• DeltaHistoryManager is requested to getFirstCommitAndICTAfter and getHistoryImpl
• OptimisticTransactionImpl is requested to commitLarge
• Snapshot is requested to getInCommitTimestampOpt
• DescribeDeltaDetailCommand is requested to describeDeltaTable
• VacuumCommandImpl is requested to setCommitClock
