Work Description: mxm commented on issue #7359: [BEAM-4681] Address
synchronization issue for portable timers
URL: https://github.com/apache/beam/pull/7359#issuecomment-450487164
>Out of curiosity, how did you discover this issue? Might be worth to add a
comment to the JIRA ticket.
I found the issue while writing the test for #7362. The test solely uses
timers in the first operator, without any state requests. The state requests
would otherwise initialize the state backend key which is required for keying
the pending timers map state. I got a "key not initalized" error. In cases with
a key initialized by the state requests, this would have caused pending timers
to be associated with the wrong key which would have led to problems deleting /
resetting them.
Adding this also to the JIRA.
