Request-per-second limits for data plane operations

Pinecone now enforces request-per-second rate limits on data plane operations (query, upsert, delete, and update) at the namespace level. These limits are set to 100 requests per second per namespace for all plans and provide protection against excessive request rates.Request-per-second limits are enforced in addition to existing read unit and write unit limits. If you exceed a request-per-second limit, you’ll receive a 429 - TOO_MANY_REQUESTS error.For more information, see Database limits.

Pagination support for fetch by metadata

The Fetch by metadata operation now supports pagination, allowing you to fetch large result sets in multiple requests. Use the paginationToken parameter to retrieve the next page of results.When there are more results available, the response includes a pagination object with a next token. Pass this token as the paginationToken parameter in subsequent requests to fetch the next page. When there are no more results, the response does not include a pagination object.For more information, see Fetch records by metadata.
