The Definitive Guide says:
Small segments are merged into bigger segments, which, in turn, are merged into even bigger segments.
Because my cluster has a lot of index,so there are a lot of segments,every segment consumes file handles, memory, and CPU cycles,so the usage of
heap size always over 65%,so the cluster do
I want to reduce the number of segments,but don't want to use
Can i set the min size of the segment,then it will be merged?
