We were benchmarking elastic search on our production cluster and we were
experimenting on refresh interval optimal values.
We had cluster of 3 machine all 32 Gb memory and 8 core. We have given 24Gb
to ES to run.
In out bench mark we are making a store document request with 50 thread
from 2 different server. We have only 5 indices with 5 primary shard and 2
a. When we put refresh interval value as 60sec we are getting 95% as
~300ms when storing a document and having load average on all the system as
b. When we put refresh interval value as 1sec we are getting 95% as ~9ms
when storing a document and having load average of 1.2.
I used to think putting more value of refresh interval would give us better
result but this is not happening in this case.
Can any one explain me why is that happening
When a node from a cluster goes down its primary shards are distributed
on other active servers in the cluster. When that comes up the shards are
distributed again to the server 'but' it doesn't have primary shards. I
want to know when would distribution of primary shard take place ?
Thanks in advance
