[jira] [Created] (FLINK-2339) Prevent asynchronous checkpoint calls
from overtaking each other
Stephan Ewen created FLINK-2339:
-----------------------------------
Summary: Prevent asynchronous checkpoint calls from overtaking each other
Key: FLINK-2339
URL: https://issues.apache.org/jira/browse/FLINK-2339
Project: Flink
Issue Type: Improvement
Components: TaskManager
Affects Versions: 0.10
Reporter: Stephan Ewen
Assignee: Stephan Ewen
Fix For: 0.10
Currently, when checkpoint state materialization takes very long, and the checkpoint interval is low, the asynchronous calls to trigger checkpoints (on the sources) could overtake prior calls.
We can fix that by making sure that all calls are dispatched in order by the same thread, rather than spawning a new thread for each call.
