Munagala V. Ramanath commented on APEXCORE-664:
-----------------------------------------------

The data structure to hold requests is a Circular Buffer of hardcoded size 1024 
in OperatorContext. This causes an exception in the container code when the 
number of requests exceeds this number.

> Large number of operator requests can overflow client buffers

> There is a limit on the number of operator requests a container can handle in 
> one stram request. However, this limit is not honored by stram, which can 
> send an unbounded number of requests. Stram should handle this correctly and 
> also have an upper bound on number of pending requests.
