Hello,
The LZ4_RAW codec specification has been merged in parquet-format (*) and should allow for better interoperability between implementations compared to the current LZ4 codec (**). (*) https://github.com/apache/parquet-format/pull/168 (**) see parquet-dev discussion on https://mail-archives.apache.org/mod_mbox/parquet-dev/202102.mbox/%3C20210216151401.7647ce37%40fsol%3E Before this new codec can have an implementation released, though, a new release of parquet-format should be done. What do you think? Am I right in assuming doing a release falls on the shoulders of the PMC? Best regards Antoine.
