  1. Set the compression.codec configuration property in the Teradata Access Module for Kafka initialization string with one of the following values:
    • none
    • gzip
    • snappy

    Specify -CONFIG compression.codec=gzip to enable gzip compression of messages in the export scenario, and decompression of gzip compressed messages in the import scenario.

    The Teradata Access Module for Kafka passes the configuration option to librdkafka, a third-party open source library, and librdkafka performs the compression and decompression on messages based on the configuration setting.
