Summary

  • Added a join_runtime_filter_probe_ratio_threshold setting (default 3) with getter so the probe/build ratio gate is user-configurable.
  • Propagated this threshold through runtime-filter planning and execution paths (new hash join, legacy pipelines, and converter) so filters are enabled only when a probe target’s estimated rows exceed the ratio.

Tests

  • Unit Test
  • Logic Test
  • Benchmark Test
  • No Test -Explain why

Type of change
