Subject Garbage collection concerns with Task Manager memory
Date Wed, 18 Oct 2017 09:40:45 GMT
I read in the Flink documentation that the TaskManager runs all tasks within its own JVM, and
that the recommendation is to set the taskmanager.heap.mb to be as much as is available on
the server. I have a very large server with 192GB so thinking of giving most of it to the
Task Manager.

I recall that there are concerns with long stop-the-world garbage collection pauses about
allocating too much memory to a JVM - is this still a concern with G1 ?
