You will not gain much advantage because ES already compresses data on disk with LZF, ZFS is using LZ4, which compression output is quite similar. In the file system statistics you will notice the compression ratio, and this will be no good value. So instead of having ZFS trying to compress where not much can be gained, you should switch it off.
