Minimal memory footprint

hi there,

I am wondering what could be the minimal memory allocated ES to be running on Windows? I tried to use this setting in the es batch script but it seems like it is using more than it is allocated:

how?

Thanks

Any comments?

The data volume is very low and no SLA is needed. Just want to reduce the footprint.

That setting specifies the amount of heap available to Elasticsearch. Elasticsearch however required off-heap memory and some file system cache as well to operate so will always use more memory than the heap specifies.

thanks,

any best practice to minimize the system resource of ES given that the seach demand is minimal?

or I should use the pure opensource version of ES?

The requirement for off-heap memory applies to any Elasticsearch version so I would not expect changing version to make much difference.
