MATRIXX Event File (MEF)
A list of events (both usage and non-usage) generated during transaction processing. Each
MEF has a corresponding transaction log file from which its data was extracted. A MEF
includes details for all Event Detail Records (EDRs) in an event type hierarchy. Balance
tracking information is contained in the events themselves. MEFs contain events that
organized by the global transaction counter (GTC) value. You can control when MEFs are
generated by specifying limits on time, number of events, or file size.
