New Kinesis Client Library 3.0 reduces stream processing compute costs by up to 33%

The article discusses the new Kinesis Client Library (KCL) 3.0, which reduces compute costs for stream processing applications by up to 33% compared to previous versions.

Specifically, the article covers:

• KCL 3.0 introduces an enhanced load balancing algorithm that automatically redistributes workload across stream processing workers, ensuring even CPU utilization and eliminating the need for over-provisioning.
• KCL 3.0 is built with AWS SDK for Java 2.x, improving performance and security while removing dependency on AWS SDK for Java 1.x.
• KCL simplifies the development of stream processing applications with Amazon Kinesis Data Streams by managing tasks like load balancing, fault tolerance, and service coordination.
• Existing applications running on KCL 2.x can upgrade to KCL 3.0 by replacing the library without changing application code.
• KCL 3.0 supports stream processing applications running on Amazon EC2 instances or containers like Amazon ECS, Amazon EKS, or AWS Fargate.
• Conclusion: KCL 3.0 is available with Amazon Kinesis Data Streams in all AWS regions, enabling cost savings and improved performance for stream processing applications.
