Nifi PutFile processor Controlling the Max file count

[brundesh]

Hi,

We are using Nifi for getting the data from mongoDB and store them in 
LFS. Actually we trying to explore more features of Nifi.

While storing the data in LFS, Nifi is generating one file each for 
document. If i am not specifying Max file count property in PutFile 
processor it is generating  same files continuously, i.e if i have 10 
documents it is creating the same documents again and again.

If i specify any value for the Max File count say 10 then it will only 
fetch only 10 documents it will ignore the rest.

I want to understand how to limit the file count to number of documents 
in mongoDB collection and increase the number of documents as data grow
