use of org.apache.flink.runtime.deployment.TaskDeploymentDescriptor.MaybeOffloaded in project flink by apache.

the class IntermediateResult method clearCachedInformationForPartitionGroup.

    // 1. The ConsumedPartitionGroup is released
    // 2. Its producer encounters a failover
    // Remove the cache for the ConsumedPartitionGroup and notify the BLOB writer to delete the
    // cache if it is offloaded
