Hope all are doing well
Currently Elastic 7.6 is running on cluster with 3 nodes and it's having 5M records in it.
While performing the Full rebuild of indexed is taking huge amount of time. But other server metrics like CPU and GC is within the limit
And similarly I had tried ES re index process which is also time consuming. Applied few workarounds like by setting Refresh interval to -1 and Replica to 0 but it still takes very long time.
I have almost 168 shards bt the segment count is lil more which is showing 800+.
Kindly help and suggest to resolve this issue. Any leads would be much appreciated.
