I've set my threadpool setting as follows:
...but I'm still seeing ~40 threads in htop.
I have 1 node w/ 1 shard and 0 replicas on es 0.19.7. Either my settings
are being ignored or I'm missing something.
My overall goal is to reduce the es memory footprint (I've set min/max mem,
reduced to 1 shard) ... is there anything else I should be doing to reduce
es memory consumption?
