Hi, There are no particular settings to set when using doc values, just make sure to not give too much memory to your JVM so that the operator system's filesystem cache has enough memory to do its job. If your previous setup didn't leverage doc values, it is likely that switching to doc values will significantly reduce memory requirements, so you could consider decreasing your ES\_HEAP\_SIZE. In addition to giving more memory to the filesystem cache, this will also reduce garbage collection times.
