Whether to use G1GC or not for 30GB heap?

As per the article :

https://www.elastic.co/guide/en/elasticsearch/guide/current/_don_8217_t_touch_these_settings.html

It suggests not to switch to G1GC . please suggest if this still holds true or ES is suggesting now to use G1GC?

The docs still say no, so there's your answer :wink:
