Kinesumer

Kinesumer is a simple Go client library for Amazon AWS Kinesis. It aims to be a native Go alternative to Amazon's KCL. Kinesumer includes a tool (called kinesumer) that lets you tail Kinesis streams and check the status of Kinesumer workers.

Features

• Automatically manages one consumer goroutine per shard.
• Handles shard splitting and merging properly.
• Provides a simple channel interface for incoming Kinesis records.
• Provides a tool for managing Kinesis streams:
  • Tailing a stream
