-----------------------------------
Summary: Abstract BarrierBuffer to an exchangeable BarrierHandler
Key: FLINK-2406
URL: https://issues.apache.org/jira/browse/FLINK-2406
Project: Flink
Issue Type: Sub-task
Components: Streaming
Affects Versions: 0.10
Reporter: Stephan Ewen
Assignee: Stephan Ewen
Fix For: 0.10
We need to make the Checkpoint handling pluggable, to allow us to use different
implementations:
- BarrierBuffer for "exactly once" processing. This inevitably introduces a
bit of latency.
- BarrierTracker for "at least once" processing, with no added latency.
