I have a Mule flow which processes files in an inbound folder that are named AAA_[id_number].dat. However, I need to configure Mule to only process this file when a corresponding file named [id_number].dat is also available. The second file indicates that the first is ready for processing.
Is there a way I can configure an inbound endpoint in Mule to only start processing the AAA_ file when it's counterpart is present? The [id_number].dat file is purely for notification purposes, it should not be processed by Mule. The inbound endpoint has a regex filter to look for a file in the format AAA...
