This is the core part of KCL by implementing worker.
It has exactly the same interface as Amazon's KCL. Internally,
it uses code from GoKini in order to get the library
functionaly quickly.
This is a working version. The test code worker_test.go
shows how to use this library.
Dynamic resharding feature is out of the scope of M4.
Test:
1. A Kinesis stream named "kcl-test" has been created under photon-infra
account.
2. Download your AWS Credential from IAM user page.
3. Modify the worker_test.go to fill in your aws credential.
4. hmake test
