Details around your use case may be helpful.

The SplitText processor will output all FlowFiles produced at the exact same time to the "splits" relationship.  So if you intent is to wait until all splits from a single source FlowFile are produced before processing those splits, this flow is not needed.

Pierre has written an excellent blog around using wait and notify processors in a dataflow that does merge and split.  Check it out here:
