I assume this is a long-debated topic but I was kind of puzzled by this recommendation:
Modifying advanced settings is generally not recommended and could negatively impact performance and stability. Using the Elasticsearch-provided defaults is recommended in most circumstances.
Does this mean for example, that, when using pretty large nodes (in the likes of
64G RAM), it is still recommended to leave the
Xmx values to their defaults? Doesn't having so low Xm* values in a context of such a large resident memory limit the potential of the stack?
