requires the rerank-cache license feature

The rerank cache stores cross-encoder rerank scores for a query and document pair in a retrieval pipeline, so a repeated pair does not have to be scored again. RERANK.GET returns the value stored under key, which must match byte for byte. In an existing namespace, each call counts as a hit or a miss in RERANK.STATS. An expired entry counts as a miss.

Return value

Section titled “Return value”
Case RESP2 RESP3
Hit Bulk string: the cached value Same
Miss, expired entry, or unknown namespace Nil bulk string Null

Errors:

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