> This is because chunks written uncompressed end up below the compressed size threshold. Demonstrated by applying the attached patch meant to improve the testing of the 10520 changes, and running {{CompressedSequentialWriterTest.testLZ4Writer}}.
> The default {{min_compress_ratio: 0}} is not affected as it never writes uncompressed.
