DEFAULT_CHANNEL_CAPACITY for each mailbox is set to 5. 5 is a pretty small number. Whenever we have a MailboxSendOperator that produces more than 5 block really fast before MailboxReceiveOperator has a chance to run, we will run into error since MailboxSendOperator doesn't retry. Propose solution 1) Increase the DEFAULT_CHANNEL_CAPACITY. This is easy to do. but this will add memory pressure 2) Return an non-op block after mailbox send reaches 5. this is ideal. however, it needs some coordination to make it happen. @walterddr @ankitsultana FYI -- This is an automated message from the Apache Git Service.
