Big Data Blog

This article discusses Kinesis Client Library (KCL) 3.0, which allows you to reduce compute costs for stream processing applications with Kinesis Data Streams by up to 33%.

Specifically, the article covers:

  • Load balancing challenges in stream processing with previous KCL versions, leading to uneven worker utilization and higher costs
  • New load balancing algorithm in KCL 3.0 that monitors worker CPU utilization and rebalances load for even utilization
  • Other benefits like reduced DynamoDB read capacity costs, graceful shard handoff, and removing AWS SDK for Java 1.x dependency
  • Steps to migrate from KCL 2.x to 3.0 with no code changes
  • Checklist of key considerations when using KCL 3.0
