-Consume an AWS Kinesis Stream and relay into CrateDB.

+Using an AWS Lambda, consume an AWS Kinesis Stream of CDC data, and relay
+into CrateDB, re-materializing the original information into an OBJECT
+column `data`.
 
-In order to run, this module/program needs the following 3rd party
-libraries, defined using inline script metadata.
+Currently supported CDC message formats:
+
+- AWS DMS
+- AWS DynamoDB
+
+Details:
+When using `ON_ERROR = exit`, the processor uses Linux exit codes for
+signalling error conditions, see https://stackoverflow.com/a/76187305.
