i am trying to store the events(present in s3 bucket) to redshift database.
Below is my architecture
JavaScript Tracker --> Scala Stream Collector --> Stream enrich --> kinesis S3 --> S3 -> EmrEtlRunner (shredding) -> Redshit
Till EmrEtlRunner(shredding) i have completed successfully with my full efforts.
Now in the last step i,e, storing events in database i,e Redshift
Below is the configuration details of Storage(redshift)
Config.yml file is below:
