Hello Team In our offlinetable we have many many small segments which is per hour .I,e segment created perhour.Some time we get 20 to 50 records., is there any Minion task configuration to merge smaller segments to larger segment where segment is older than 30 days,Also how minion job will triger what configuration I need to follow.

yes using mergeRollup task in offline table config, you can merge smaller segments into larger one. but table config is not enough. you need to tweak some controller config
