requires the feature-store license feature

The feature store keeps typed feature values for entities (users, items, sessions) in named feature groups, for low-latency reads at model inference time. FEATURE.STATS reports counters for one group. For a group that does not exist, every counter is zero.

Return value

Section titled “Return value”

The reply is a flat array of alternating field names and values in both RESP2 and RESP3 (it is not sent as a RESP3 map). The fields, in order:

Field Type Meaning
entities Integer Entities stored.
totalReads Integer Entity reads (FEATURE.BATCH counts one per entity).
totalWrites Integer FEATURE.SET calls.
memoryBytes Integer Approximate memory used.

Errors:

  • ERR wrong number of arguments for 'feature.stats' command if the argument count is wrong.
  • NOLICENSE feature-store requires a HotKV license. Contact sales@hotkv.com if your license does not include the feature-store feature.
