Delete Vector Index

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.
