Summary
Replace deprecated
spark.indextables.mergeOnWrite.mergeGroupMultiplierwithspark.indextables.mergeOnWrite.minBatchesToTriggerin thedocs/reference/features.mdexample. Closes #237.The deprecation note in
docs/reference/configuration.md:163directs users frommergeGroupMultipliertobatchCpuFraction + minBatchesToTrigger.minBatchesToTrigger=2is the closest 1:1 substitute for the originalmergeGroupMultiplier=2.0— both raise the merge trigger threshold by 2× over the default.Scope
Documentation-only change; no code or tests affected.
Test files under
src/test/scala/.../merge/still reference the deprecated key (~30 occurrences). Those weren't touched here per the issue's scope (docs/reference/features.mdline 185) — happy to follow up in a separate PR if test migration is desired.Verification
