I seem to be struggling to get data into my Elasticsearch cluster fast enough and it seems the bottleneck is that elasticsearch-jdbc is only utilising 1 cpu.
Is there anyway of configuring it to be multithreaded? I'm not great with Java, so don't know what to tweak on this one.
I'm using elasticsearch 2.3.1-1 and elasticsearch-jdbc 2.3.1.0 on CentOS 7.2 (x64)
