Add/Enhance CustomCode Transformation Node (JavaScript / .NET) in Fabric Eventstream

Most customers today rely on custom functions written in JavaScript (UDF/UDA) in Azure Stream Analytics, and we are looking for similar capabilities in Eventstream. To address your questions: 1)We should enhance the Custom Code (SQL) capability by introducing support for user-defined functions, allowing transformations similar to Azure Stream Analytics. 2) Processing can be handled for both scenarios, depending on the event message type. 3) The SQL code can be extended in a flexible way to support multiple downstream use cases, such as writing to output or passing data to the next processing stage. For example: SELECT UDF.JavaScriptFunction(InputStream) AS sampleResult INTO output FROM InputStream For reference, refer Azure Stream Analytics supports JavaScript-based user-defined functions that enable complex transformations using built-in JavaScript capabilities. Here is the documentation link: https://learn.microsoft.com/en-us/azure/stream-analytics/stream-analytics-javascript-user-defined-functions

Interesting ask. 1/ What would you want to run inside this node -- ie what type of transform? 2/ do you want to process one or many events at once? 3/ where would you want to write the output to? To another stream? or ?
