Zhipeng Zhang updated FLINK-27535:
----------------------------------
Fix Version/s: (was: ml-2.1.0)
> Optimize the unit test execution time
> -------------------------------------
>
> Key: FLINK-27535
> URL: https://issues.apache.org/jira/browse/FLINK-27535
> Project: Flink
> Issue Type: Improvement
> Components: Library / Machine Learning
> Reporter: Dong Lin
> Assignee: Yunfeng Zhou
> Priority: Critical
>
> Currently `mvn package` takes 10 minutes to complete in Github actions. A lot
> of time is spent in running unit tests for algorithms. For example,
> LogisticRegressionTest takes 82 seconds and KMeansTest takes 43 seconds in
> [1].
> This time appears to be more than expected. And it will considerably reduce
> developer velocity if a developer needs to wait for hours to get test results
> once we have 100+ algorithms in Flink ML.
> We should understand why it takes 82 seconds to run e.g.
> LogisticRegressionTest and see if there is a way to optimize the test
> execution time.
