Tuning Flink Clusters for Stability and Efficiency

Tuning Flink Clusters for Stability and Efficiency

摘要

At Pinterest, stream data processing powers a wide range of real-time use cases. Our Flink clusters are multitenant and run jobs that concurrently process more than 20M msgs/sec across 12 clusters. Over the course of 2022 and early 2023, we’ve spent a significant period of time optimizing our Flink runtime environment and cluster configurations, and we’d like to share our learnings with you.
