-------------------------------------
Summary: Support synchronized processing time in Flink runner
Key: BEAM-1641
URL: https://issues.apache.org/jira/browse/BEAM-1641
Project: Beam
Issue Type: Bug
Components: runner-flink
Reporter: Kenneth Knowles
Assignee: Aljoscha Krettek
The "continuation trigger" for a processing time trigger is a synchronized
processing time trigger. Today, this throws an exception in the FlinkRunner.
The supports the following:
- GBK1
- GBK2
When GBK1 fires due to processing time past the first element in the pane and
that element arrives at GBK2, it will wait until all the other upstream keys
have also processed and emitted corresponding data.
Sorry for the terseness of explanation - writing quickly so I don't forget.
