Avro PostAssembler

This operator allows you to create Avro, CSV, or Json messages from the Vora messages containing record objects. This operator can be used as the inverse operator of the Vora Avro Decoder operator to reconstruct the original messages, or the equivalent messages in another format or in different structures. The schema must be provided as an Avro schema in this operator's configuration or included in the message itself under attribute "avro.schema". This schema is used to assemble the input data into the target output message.
