Elasticsearch Heapsize query

HI Team,

Can we configure heap size morethan 50 % of RAM Size.If we have 64 GB RAM can we configure >32 GB say 48 GB .?


It's not recommended.
Also going above 30gb is a waste of resources as the jvm will use 64bits memory pointers instead of 32bits.

Why would you like to do this?
