Hi Ron, Thanks for the feedback.
For instance, Kinesis connector versions 1.15.3 and below (for Flink 1.15) have a known bug that can lead to a deadlock. The plugin will warn the user (or fail the build) if app developers are using Kinesis connector 1.15.3 or below (and Flink 1.15). Another example is the MSK IAM Auth library. There is a known bug related to classloaders which, once triggered, lead to Flink apps restarting continuously. The plugin detects if the version of the MSK IAM Auth lib being used is a buggy one and warns the developer or fails the build. I understand the use of word “compatibility” is probably misleading here. The idea is to make this a database of known issues detectable during build/packaging. It’ll be a collaborative effort!

Intuitively though, I don't really see what type of compatibility issues it's trying to solve, can you explain in a bit more detail? Is it solving compatibility issues within the Flink project itself, or compatibility issues with the Flink code that the user app depends on? Best, Ron Kartoglu, Emre <kar...@amazon.co.uk<mailto:kar...@amazon.co.uk>> 于2023年9月15日周五 22:48写道： Hello Flink users, We recently released a Maven plugin that detects known Flink issues at packaging/compile time: https://github.com/awslabs/static-checker-flink Its scope is currently limited to finding known connector incompatibility issues. Some future ideas: * Check for other statically detectable issues e.g. setting Flink operator ids. * Gradle plugin * Simple CLI tool to detect the issues in jar files (not couples with any build tool) This came out of a Hackathon, so the code needs a lot of improvement (please feel absolutely free to raise a PR). Please let know if you have any feedback. Emre
