Transformations Configuration
You can configure any number of transformations to run on the data one after another - transformations will run in the order provided. (You can repeatedly specify the same transformation more than once, if needed.) All transformations operate on a single message basis.
If you're filtering the data, it's best to provide the filter first, for efficiency.
If you're working with Snowplow enriched messages, you can configure scripting transformations, or any of the built-in transformations, which are specific to Snowplow data.
If you're working with any other type of data, you can create transformations via scripting transformations.
Transformations and filters
Transformations modify messages in-flight. They might rename fields, perform computations, set partition keys, or modify data. For example if you wanted to change a snake_case field name to camelCase, you would use a transformation to do this.
Filters are a type of transformation which prevent Snowbridge from further processing data based on a condition. When data is filtered, Snowbridge will ack the message without sending it to the target. For example if you only wanted to send page views to the destination, you would set up a filter with a condition where event_name matches the string page_view.
Transformation Configuration
To configure transformations, supply one or more transform {} block. Choose the transformation using use "${transformation_name}".
Example:
The below first filters out any event_name which does not match the regex ^page_view$, then runs a custom javascript script to change the app_id value to "1"
