Hi dev@, Last week we had a twofer: e2e tool and integration test validating the contract of column indexes/indices (if all values are between min and max and if set whether the boundary order is correct). There are some takeaways and corrections to be made to the former (like the max->min typo) - thanks for the feedback on that!
The next installment is also an integration test that tests the filtering logic on files including simple and special cases (user defined function, complex filtering, no filtering, etc.). https://github.com/apache/parquet-mr/blob/e7db9e20f52c925a207ea62d6dda6dc4e870294e/parquet-hadoop/src/test/java/org/apache/parquet/hadoop/TestColumnIndexFiltering.java Please let me know if you have any questions/comments. Best, Anna
