CDRs
The writing of CDRs to file is now supported in the following modes:
- Correlate: The submission and delivery receipt (DLR) details are contained in each line of the CDR file. These entries are written after the DLR is received.
- Operation: The submission and delivery receipt (DLR) details are on separate lines of the CDR file. The submission line is written the message ID is returned from the target. The DLR line is written when the delivery receipt is received.
CDRs are written in batches for performance purposes. Both CDR modes have been tested up to 5000 TPS.
Further enhancements will be made to the writing of CDR files. Additional CDR sinks (Kafka, webhook, etc) are expected to be added in due course.
See configuring CDRs in the documentation.
