Hi Iceberg Community, I saw in the Puffin spec <https://iceberg.apache.org/puffin-spec> that the footer of the Puffin file or the blobs themselves could be compressed by LZ4. I checked the code <https://github.com/apache/iceberg/blob/main/core/src/main/java/org/apache/iceberg/puffin/PuffinFormat.java#L110> however, and for me it seems that currently LZ4 is not supported. My first question is do I miss anything here? The second, is if we in fact don't support LZ4, can I remove it from the spec to avoid confusions? (I believe this requires a vote in a separate thread)
Thanks, Gabor
