Drop ANN Index

AI-generated

Summary

Delete the IVF approximate-nearest-neighbor index for a collection. The operation checks whether an index exists, drops it, and flushes the store; it does not remove the collection’s vectors.

Inputs

  • Read Only — Defaults to false. When enabled, rejects this write operation before it runs.
  • Collection (required) — Name of the collection whose ANN index to drop.

Output shape

A single item with collection and dropped fields.

dropped is true if the collection had an ANN index and false if it did not. Errors are returned as an error item when Continue On Fail is enabled; otherwise the node raises an operation error.
