Summary: [C++] [Python] Set up testing for backwards compatibility of the parquet reader Key: ARROW-5915 URL: https://issues.apache.org/jira/browse/ARROW-5915 Project: Apache Arrow Issue Type: Test Components: C++, Python Reporter: Joris Van den Bossche Given the recent parquet compat problems, we should have better testing for this. For easy testing of backwards compatibility, we could add some files (with different types) written with older versions, add them to /pyarrow/tests/data/parquet (we already have some files from 0.7 there) and ensure they are read correctly with the current version. Similarly as what Kartothek is doing: https://github.com/JDASoftwareGroup/kartothek/tree/master/reference-data/arrow-compat -- This message was sent by Atlassian JIRA (v7.6.14#76016)
