    Details

    • Release Note:
      Hide
      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.
