Hello
My configuration is:
6 nodes Elasticsearch cluster
OS: Centos 6.5
JVM: 1.7.0_25
Cluster is working fine. I can indexing data, query, etc. Now I'm doing
test on package about ~50mln doc (~13GB). I would like take better
performance during indexing data. To take this target I has been changed
parameter refresh_interval. I did test for 1s, -1 and 600s. Time for
indexing data is that same. I checked configuration (_settings) for index
and value for refresh_interval is ok (has proper value), eg:
{
"smt_20140501_100000_20g_norefresh" : {
"settings" : {
"index" : {
"uuid" : "q3imiZGQTDasQUuMWS8oiw",
"number_of_replicas" : "1",
"number_of_shards" : "6",
"refresh_interval" : "600s",
"version" : {
"created" : "1020199"
}
}
}
}
}
Create index, setting refresh_interval and load is done on that same
cluster node. Before test index is deleted and created again before start
new test with new value of refresh_interval. All cluster nodes logs
information that parameter has been changed, eg:
[2014-07-16 11:24:09,813][INFO ][index.shard.service ] [h6]
[smt_20140501_100000_20g_norefresh][1] updating refresh_interval from [1s]
to [-1]
or
[2014-07-16 11:32:32,928][INFO ][index.shard.service ] [h6]
[smt_20140501_100000_20g_norefresh][1] updating refresh_interval from [1s]
to [10m]
After start test new data are available immediately and indexing time that
same in 3 cases. I don't know where is failure. Somebody know what is going
on?
Regards
Marek
