Group	Postexecution
Function	This postexecuter can encode data in the AVRO format.
Configuration file	None. Configuration is done directly with a string in field Config file.

Description

This postexecuter can encode data in the AVRO format using a schema file and is primarily used for this purpose in conjunction with the Response Route Kafka (see there), but can also be used with others.

The path to the schema file is specified in field Config file.
