Hi Chia-Ping, Thanks for following up on this!
The `remote.log.manager.thread.pool.size` was initially planned to be deprecated as part of KIP-950 <https://cwiki.apache.org/confluence/display/KAFKA/KIP-950%3A++Tiered+Storage+Disablement>, then it was repurposed to use it as followerThreadPool in KIP-1030 <https://cwiki.apache.org/confluence/display/KAFKA/KIP-1030%3A+Change+constraints+and+default+values+for+various+configurations#KIP1030:Changeconstraintsanddefaultvaluesforvariousconfigurations-#9#10#11Config(s):remote.log.manager.copier.thread.pool.size/remote.log.manager.expiration.thread.pool.size/remote.log.manager.thread.pool.size> .
