Summary

Currently, the EXPLAIN output doesn't explicitly show the runtime filters that are applied during query execution. Displaying runtime filter information would significantly help in:

  • Analyzing query performance optimization
  • Understanding filter propagation between scan nodes
  • Debugging query execution efficiency

Proposed Solution:

Add runtime filter information to EXPLAIN output including:

  • Applied runtime filter identifiers
  • Filter types (IN/BLOOM_FILTER/MIN_MAX etc.)
  • Source expressions/tables
  • Target scan nodes
  • Filter effectiveness statistics (optional)
