I’ve the configuration for files in pg database, with information like file source, destination, file pattern and etc..
And I want to have a nifi process where I’ll read configuration via db and then provide this information in attributes to the another processors which will transfer file from source to destination.
I have the following flow in Nifi:

1. ProcessorQueryDatabaseTableRecord. (Reading configuration from db like source + destination)
2. SplitRecord. Splitting data per configuration record.
3. EvaluateJsonPath. To fetch configuration into attributes.
   And then I have a problem… I cant provide pattern/regexp to fetchFile processor, there is only path and filename (I dont know exact name).
   To get exact filename by pattern I have to use listFile, but ListFile does not accept incoming connections.

Can someone recommend what kind of processors and flow I should use to transfer files dynamically based on db configuration?

Thank you in advance guys!
