--------------------------------------

[~trohrmann] Thanks, till, can I create a Jira for this? I think we should 
support both fixed allocator and dynamic allocator(dynamically allocating in a 
range) in flink, this is especially import for users that share the 
resources(e.g. in Yarn mode), otherwise, one big query or job may occupy all 
the resources and  cause other jobs block. Also, it's inconvenient for 
benchmark testing. Maybe I can help to do or participate in this work.
