StandbyTask createTask( final Consumer<byte, byte> consumer, final TaskId taskId, final Set<TopicPartition> partitions)
StandbyTaskCreator always records when requested to create a task for monitoring purposes, but creates a standby task only for processor task topologies (for which it was created) with at least one state store.
StandbyTaskCreator takes the following to be created:
ProcessorTopology has no state stores,
createTask simply prints out the following TRACE message to the logs and returns
Skipped standby task [taskId] with assigned partitions [partitions] since it does not have any state stores to materialize
