shuai.xu updated FLINK-4256:
----------------------------
Description:
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.
