jihoonson commented on issue #5979: Kafka Indexing Service lagging every hour
   1. That SQL is to list all _used_ (live) segments falling in an interval, 
and it can be called 1) whenever a new segment is allocated in KIS and 2) when 
a taskLock is acquired in batch ingestion (like index or merge tasks). 
   a. Yes, you can delete them, but I would recommend to use the kill task 
rather than manually deleting rows. You can set `druid.coordinator.kill.on` to 
true for coordinators to periodically kill segments. Please check 
 for details.
   b. I haven't tested, but sounds making sense. 
   2. The `druid_tasklogs` is not actually being used, so you can freely delete 
all entries in that table. Please check 
https://github.com/apache/incubator-druid/issues/5859. For `druid_tasks`, yes 
you can delete old entries from that table. One thing I'm curious is, do you 
have an actual issue of too large `druid_tasks` table? or are you just checking 
all tables?
