Delete Vector Index

DELETE

Delete an existing vector similarity search index.

This endpoint removes the specified index from the database. Important considerations:

  • Deletion is permanent and cannot be undone
  • Underlying vector data remains intact
  • Queries will fall back to sequential scan
  • Running queries during deletion may be slower
  • Use run_with_orchestration=True for large indices to prevent timeouts
  • Consider index dependencies before deletion

The operation returns immediately but cleanup may continue in background.
