koro is a simple DynamoDB Streams reader for Go.
In real environment, most of people prefers to Lambda function to read DynamoDB Streams because the lambda handles shards management. The lambda function itself is kept in stateless. I'd want to have a similar setup in local environment (mainly for testing) but there is no Lambda runtime environment that works with DynamoDB Steams.
koro is built to allow to read DynamoDB Streams on DynamoDB Local with less hustle.
See stream_test.go for the detail.
