-----------------------------------
Summary: Fine-grained recovery
Key: FLINK-4256
URL: https://issues.apache.org/jira/browse/FLINK-4256
Project: Flink
Issue Type: Improvement
Components: JobManager
Affects Versions: 1.1.0
Reporter: Stephan Ewen
Assignee: Stephan Ewen
Fix For: 1.2.0
When a task fails during execution, Flink currently resets the entire execution
graph and triggers complete re-execution from the last completed checkpoint.
This is more expensive than just re-executing the failed tasks.
In many cases, more fine-grained recovery is possible.
The full description and design is in the corresponding FLIP.
