Recommended Heap - Documentation Error?

[Rylon]

Hi,

Just a quick one, I was reviewing the notes on recommended maximum heap sizes, but noticed one document states 32GB where another states 30.5GB. I assume it's 30.5GB since that is the latest recommendation from Oracle?

Thanks!

This issue was moved to elastic/elasticsearch-definitive-guide#426

It depends on the JVM - some cut over to uncompressed pointers at different heap sizes. 30.5GB is likely to be safe

Yeah, that makes sense. I just thought it was worth raising so that the docs are consistent.

@Rylon Agreed - I just moved the issue to the right repository
