Hello Gang, I've recently had some space to look at Avro again recently (I enjoy contributing to something that has such a wide industry impact).
In thinking about the block format of Avro, it currently stores Metadata about the number of records in each block. I'm performing a thought exercise of replacing the count field with a map and allowing for a more generic set of metadata. In particular, would want to add better scan support: Bloom filters, min, max values. Making this backwards compatible looks hard at first, but does anyone in the community see value here? Thanks.
