-----------------------------------
Summary: Only use dedicated/named classes for mailbox letters.
Key: FLINK-14199
URL: https://issues.apache.org/jira/browse/FLINK-14199
Project: Flink
Issue Type: Improvement
Reporter: Arvid Heise
Attachments: Screenshot 2019-08-22 at 12.59.59.png
Unnamed lambdas make it difficult to debug the code

Note: there are cases of the mailbox usage that need a Future to track when a
letter is executed and get success/exception result. Current implementation (in
MailboxExecutor) piggybacks on java.util.concurrent.FutureTask and the fact
that it implements Java Executor api.
