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.
