[jira] [Commented] (APEXCORE-664) Large number of operator requests can overflow client buffers

["Munagala V. Ramanath (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/APEXCORE-664?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15909593#comment-15909593 ] 

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.

> 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.
