Summary

This release introduces significant enhancements in observability, performance optimizations for fetching and garbage collection, and stricter validation on collection creation endpoints. It also updates error handling for billing issues in the JS client and refines tracing configurations.

Migration Steps

  1. If you rely on the HTTP status code 429 for GenericQuotaError, note that it has been changed to 422.
  2. If you are using the JavaScript client and handling 422 errors as ChromaConnectionError, update your error handling to expect QuotaExceeded instead.

✨ New Features

  • Added cache mount and tolerations to the garbage collector template in the Helm chart.
  • Added block-level metrics.
  • The /add endpoint now returns an error if embeddings are not provided.
  • The /add endpoint now requires embeddings and enforces a minimum embedding dimension.
  • Added dark mode support for the hero image.
  • Added a delete_many call to the storage API.
  • Consumed delete_many from the wal3 garbage collector.
  • Limited the number of concurrent get_all_block_ids() calls when using buffer_unordered().
  • Used the new delete_many() storage method in the DeleteUnusedFiles operator.
  • Enabled change notifier OpenTelemetry/tracing.
  • Added a pprof server to the query service.
  • Dedup inserts to the same key in foyer.
