Delete data

This page shows you how to use the delete endpoint to remove records from an index namespace.

​

Delete specific records by ID

Since Pinecone records can always be efficiently accessed using their ID, deleting by ID is the most efficient way to remove specific records.

​

Delete specific records by metadata

For pod-based indexes, you can delete records by metadata by passing a metadata filter expression to the delete endpoint.

For serverless indexes, however, it is not possible to delete by metadata. Instead, you can delete records by ID prefix.

​

Delete all records from a namespace

To delete all records from a namespace, provide a namespace parameter and specify the appropriate deleteAll parameter for your SDK. To target the default namespace, set namespace to "".

​

Delete all records from an index

To remove all records from an index, delete the index and recreate it.

​

Data freshness

Pinecone is eventually consistent, so there can be a slight delay before new or changed records are visible to queries. You can use the describe_index_stats endpoint to check data freshness.
