-----------------------------------
Summary: Improve metrics around fine-grained recovery and
associated checkpointing behaviors
Key: FLINK-7894
URL: https://issues.apache.org/jira/browse/FLINK-7894
Project: Flink
Issue Type: Improvement
Affects Versions: 1.3.2, 1.4.0
Reporter: Zhenzhong Xu
Currently, the only metric around fine-grained recovery is "task_failures".
It's a very high level metric, it would be nice to have the following
improvements:
* Allows slice and dice into which tasks were restarted.
* Recovery duration.
* Recovery associated checkpoint behaviors: cancels, failures, etc
