Purpose
Configure the table used by Flink sorted index builds with an explicit last-safe-snapshot boundary. The intent is to limit previous-commit lookups to snapshots created after the build starts, without enabling strict checks on concurrent snapshot changes.
At the start of
SortedIndexTopoBuilder.buildIndexStream:0when the table has no snapshots.commit.last-safe-snapshotto that ID on the table copy used to build the index stream.commit.strict-mode.enabledtofalseon the same table copy.Tests
No new tests are included in this PR. CI validation is pending.
