Function RM_BlockClientOnKeys

app/redis-6.2.6/src/module.c:5458–5460

This call is similar to RedisModule_BlockClient(), however in this case we * don't just block the client, but also ask Redis to unblock it automatically * once certain keys become "ready", that is, contain more data. * * Basically this is similar to what a typical Redis command usually does, * like BLPOP or BZPOPMAX: the client blocks if it cannot be served ASAP, * and later when the key rec

 *       callback in that case).
