IndexingStatus
January 16, 2026 · Chroma Cloud
When data is written to Chroma, it's first committed to our write-ahead log (Wal3), then indexed and persisted to object storage asynchronously. This architecture lets Chroma handle high-throughput writes without blocking, but until now, there was no way to know how much of your data had actually been indexed.
IndexingStatus tracks the progress of indexing operations in a Chroma collection. You can now call get_indexing_status() on any collection to see exactly where things stand.
The response includes:
num_indexed_ops: Operations that have been fully indexednum_unindexed_ops: Operations still in the WAL, pending indexingtotal_ops: Total operation count (adds, updates, upserts, and deletes)op_indexing_progress: A float from 0.0 to 1.0 representing the proportion indexed
IndexingStatus is available today on Chroma Cloud.
