Occasionally one needs to pick up and process a large number of files, on the order of hundreds or thousands. With the Batch Inbound eWay/JCA Adapter it is not possible to pick up more then one file per poll. The Batch Local File, if triggered by some event other then an appearance of a file in a directory, perhaps a Scheduler trigger of a manual trigger, with correctly designed logic can process many files in a single invocation.
The document, ProcessingHundredsOfFileWithBatchAdapter.pdf,
discusses how Batch Local File-based solution can be constructed to effectively process hundreds of files in a single pass.
