Thanks Binh.
I'm curious about this because we're benchmarking our bulk indexing. And
we've found out that the fastest bulk indexing strategy to be:
- bulk indexing with 0 replica, no refresh, let ES do as little merge as
possible - when indexing finished, optimize segments
- replicates
Is there some readings about the details/internals of lucene? We've the
book Lucene in Action but it's mainly about core concepts and usage.

The indexing buffer could also fill up which will flush to a segment. Also
the translog flush is not "exactly" deterministic, for example
"index.translog.interval" determines how often to check if the translog
needs to be flushed or not. Anyway, I wouldn't worry about it if I were
you. About the merge, I'd probably leave the defaults alone unless you are
absolutely sure changing them helps you. The more segments there are, the
more time it could take to do a merge.
