Gzip format response

Hello Everyone!

We are using consume KAFKA plug-in, however the source system is publishing data to Kafka in Gzip format. In Appian we are reading data from consume KAFKA plugin able to store kafka messages in database. The body of the Json data is in Gzip format. Can anyone suggest how to decompress the data while reading data from database. 

Example: 

{"topic":"testTopic","partition":0,"offset":23,"key":"123","value":"\u001f�\b\u0000\u0000\u0000\u0000\u0000\u0000"}

Thanks for your help!
