@DanMcCray1 Once you have the content from Kafka as a flowfile, your options are not just limited to ExecuteScript.   Depending on the type of content you can use the following ideas:   EvaluateJsonPath - if the content is a single json, and you need one or more values inside the object then this is an easy way to get those values to attributes. ExtractText - if the content is text or some raw format, extractText allows you to regex match against the content to get values to attributes. QueryRecord w/ Record Readers & Record Writer - this is the most recommended method.  Assuming your data has structure (text,csv,json,etc) and/or multiple rows/objects you can define a reader, with schema, output format (record writer), and query the results very effectively.   If you indeed want to work with Execute Script you should start here:   https://community.cloudera.com/t5/Community-Articles/ExecuteScript-Cookbook-part-1/ta-p/248922 https://community.cloudera.com/t5/Community-Articles/ExecuteScript-Cookbook-part-2/ta-p/249018 https://community.cloudera.com/t5/Community-Articles/ExecuteScript-Cookbook-part-3/ta-p/249148     If this answer resolves your issue or allows you to move forward, please choose to ACCEPT this solution and close this topic.
