Hi, How should we manage idealstate znode for a table having a large number of segments? One of our real time table has more than 18k segments and zookeeper node size is greater than 3.2 MB. zookeper is supposed to have nodes of size less than 1 MB. will it have a negative impact on pinot controller performance when it read or write (during segment completion) ideal state of the table?

Not really, but we just running the minion tasks to merge the segments and possibly move to offline table
