Chesnay Schepler closed FLINK-13223.
------------------------------------
       Resolution: Fixed
    Fix Version/s: 1.10.0
     Release Note: 
Flink will now by default use the "region" failover strategy. Flink will now 
attempt to only restart tasks that are connected to the failed task through a 
pipelined connection.

Users who were not using a restart strategy or have already configured a 
failover strategy should not be affected.

Streaming users who were not using a failover strategy may be affected if their 
jobs are embarrassingly parallel or contain multiple independent jobs. In this 
case, only the failed parallel pipeline or affected jobs will be restarted.

Batch users may be affected if their job contains blocking exchanges (usually 
happens for shuffles) or the ExecutionMode was set to BATCH or BATCH_FORCED via 
the ExecutionConfig.

Overall users should see an improvement in performance.
