Description
This pair of Processors will provide several benefits over the existing GetFile processor:
1. Currently, GetFile will continually pull the same files if the "Keep Source File" property is set to true. There is no way to pull the file and leave it in the directory without continually pulling the same file. We could implement state here, but it would either be a huge amount of state to remember everything pulled or it would have to always pull the oldest file first so that we can maintain just the Last Modified Date of the last file pulled plus all files with the same Last Modified Date that have already been pulled.
2. If pulling from a network attached storage such as NFS, this would allow a single processor to run ListFiles and then distribute those FlowFiles to the cluster so that the cluster can share the work of pulling the data.
3. There are use cases when we may want to pull a specific file (for example, in conjunction with ProcessHttpRequest/ProcessHttpResponse) rather than just pull all files in a directory. GetFile does not support this.
