2. Calls AWS Comprehend API to add sentiment to data
3. Adds records to postgres database

The other Lambda function can be scheduled to run every time interval to stream data into Kinesis Firehose.

1. Calls NewsAPI to collect data for streaming
2. Cleans NewsAPI response
3. Puts record into AWS firehose
