Hi,
do you have some experience in setting up min_index_buffer_size
and max_index_buffer_size for static indices?
In my setup 1 index per month is created:
/data-2013-01
/data-2013-02
/data-2013-03
/data-2013-04
/data-2013-05
/data-2013-06
/data-2013-07
/data-2013-08
ES is running is a cluster with 4 servers and each index has 4 shards.
Currently there exists 30 indices, 240 shards (including replicas).
Each ES instance has 16GB memory.
If I understand the docs right
(http://www.elasticsearch.org/guide/reference/modules/indices/),
index_buffer_size is set to 10% by default and this 10% is divided to all
shards.
That means: 10% of 16GB = 1,6GB / 240 shards = ~7MB per shard
Now the older indices are static and don't need too much memory. Is it a
good idea to increase - if possible - the index buffer size for the latest
index and decrease the index buffer size for static indices?
Cheers
Jonny
