object StreamingRelationStrategy extends Strategy

This strategy is just for explaining Dataset/DataFrame created by spark.readStream. It won't affect the execution, because StreamingRelation will be replaced with StreamingExecutionRelation in StreamingQueryManager and StreamingExecutionRelation will be replaced with the real relation using the Source in StreamExecution.
