             Summary: Single Task Failure Recovery Prototype
                 Key: FLINK-18112
                 URL: https://issues.apache.org/jira/browse/FLINK-18112
             Project: Flink
          Issue Type: New Feature
          Components: Runtime / Checkpointing, Runtime / Coordination, Runtime / Network
    Affects Versions: 1.12.0
         Environment: Build a prototype of single task failure recovery to address and answer the following questions:

Step 1: Scheduling part, restart a single node without restarting the upstream or downstream nodes.

Step 2: Checkpointing part, as my understanding of how regional failover works, this part might not need modification.

Step 3: Network part

  - how the recovered node able to link to the upstream ResultPartitions, and continue getting data

  - how the downstream node able to link to the recovered node, and continue getting node

  - how different netty transit mode affects the results

  - what if the failed node buffered data pool is full

Step 4: Failover process verification
            Reporter: Yuan Mei
             Fix For: 1.12.0
