    Description

      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.
