Set the number of index segments for indexing

Elastic Stack Elasticsearch
1

Hi,

While optimizing it's pretty easy to determine the number of segments by
executing Optimize command with max_num_segments parameter.
My question is about indexing prior to optimizing.
I checked the
http://www.elasticsearch.org/guide/en/elasticsearch/reference/0.90/index-modules-merge.html#tiered section
and I still couldn't find - how do I control the number of segments during
indexing? Is there a simple way to tell to ES that I am willing to pay with
indexing time and frequent merges but keep number of segments below 10, for
example?

Thanks,
Ophir

It's a bit more complex. You can use the "segments_per_tier" to limit the
number of segments to be created at a tier. Together with
"max_merge_at_once" you can control the amount of running merges.

Mike McCandless is the authority who can explain how the tiered merge
policy works:
