Did you mean the cache work on broker but not work on historical? Besides, can you provide your historical node's startup logs ? Ok I solved this problem because I didn't configure the historical druid-redis-cache to have a historical intermediate result set. But I still have a place I don't understand. After configuring the broker redis buffer, in addition to querying the intermediate result set information, the broker also has segment buffer information.
