We have monthly indexes (currently 11 months) with 22 shards per index. I
am seeing what seems to be a lot of segments per index (roughly 1200 to
1380 segments). The older indexes should have very little, if any updates
occurring on them. From everything I have read it sounds like ES should be
automatically merging segments, but now I am a bit concerned that this is
not occurring. I know we can manually run an optimize, but will need to
allocate another resource to do that work (as to not impact current
system). I am fairly new to ES (if that isn't obvious) and am really
trying to understand we have an issue or not.
Rough index stats:
22 shards per index
65 million docs per index
350 GB per index
Any info, suggestions, etc. are greatly appreciated.
