Drop Store

Description

The DropStore request deletes an entire store from the database. Once a store is dropped, all of its vectors, embeddings, and associated metadata are permanently removed. This operation is destructive and cannot be undone.

Parameters

• Store - Name of the store to delete
• ErrorIfNotExists - Controls behavior when store doesn't exist:
  • true - Returns an error if the store is not found
  • false - Silently succeeds even if store doesn't exist
