I've red this doc [ https://www.elastic.co/guide/en/elasticsearch/reference/1.7/index-modules-merge.html
] many times, but I'm not sure what is the actual result if set lower value of index.merge.policy.max_merged_segment.
Assume I have bulk indexing for 3million docs in 30 minutes.
If I set lower value than default 5GB, let's say 2.5GB,
- Will I have better index performance?
- Will I reduce number of merge that occurred?
- Will I get fewer segments files?
- Does this mean in the end, max segment file will approximate 2.5GB?
Please share your experience and thought, many thanks.
