Scala Kinesis Enrich is an [Amazon Kinesis] kinesis app, written in Scala and using the Kinesis Client Library, which:

1. Reads raw Snowplow events off a Kinesis stream populated by the Scala Stream Collector
2. Validates each raw event
3. Enriches each event (e.g. infers the location of the user from his/her IP address)
4. Writes the enriched Snowplow event to another Kinesis stream

It is designed to be used downstream of the Scala Stream Collector.

It also supports reading raw events from stdio and writing enriched events to stdout, which is useful for debugging.

Scala Kinesis Enrich utilizes the scala-common-enrich Scala project to enrich events and the SnowplowRawEvent for reading Thrift-serialized objects collected with the Scala Stream Collector.
