spEnrichedFilter
spEnrichedFilter: Specific to Snowplow data. Filters messages based on a regex match against an atomic field.
This transformation is for use on base-level atomic fields, rather than fields from contexts, or custom events — which can be achieved with spEnrichedFilterContext and spEnrichedFilterUnstructEvent.
Filters can be used in one of two ways, which is determined by the filter_action option. filter_action determines the behavior of the app when the regex provided evaluates to true. If it's set to "keep", the app will complete the remaining transformations and send the message to the destination (unless a subsequent filter determines otherwise). If it's set to "drop", the message will be acked and discarded, without continuing to the next transformation or target.
This example filters out all data whose platform value does not match either web or mobile.
