requires the negative-cache license feature

The negative cache holds negative results, such as “user not found” or “refused by moderation”, usually with a short TTL, so repeated lookups for the same missing or refused item do not reach your backend or model again. NCACHE.DROP deletes a namespace with its entries, settings and counters. To keep the namespace and only clear its entries, use NCACHE.FLUSH.

Return value

Section titled “Return value”
Case RESP2 RESP3
Namespace deleted Integer 1 Same
No such namespace Integer 0 Same

Errors:

  • ERR wrong number of arguments for 'ncache.drop' command if the argument count is wrong.
