Nifi : Implement Sleep Mechanism in nifi without Executescript

[#1]

Hi Team,

I am trying to implement for the scenario where the events should sleep for 5 minutes and let all the flow files are queued up, then check the count of the files if it is greater than 10 route to failure else route to SUCCESS.

I did in Execute script processor as below. However, i am trying to avoid the executescript for this and try to use Native nifi processors.

====== Executescript ===============

Thread.sleep(300000)
def flowFiles = session.get(100)
if (!flowFiles || flowFiles.size() <= 10) {
session.transfer(flowFiles, REL_SUCCESS)
} else {
session.transfer(flowFiles, REL_FAILURE)
}

What is the use case for wanting to hold downstream processing of FlowFiles until a min 10 are queued?  This is not a typical use pattern for NiFi.  While I am sure it could be done without using a scripting processor,I don't think it would be as efficient in terms of resources.

Creative use of the MergeContent processor comes to mind here.
