" This series adds support for the "md" sstable format. Support is based on the following: * do not use clustering based filtering in the presence of static row, tombstones. * Disabling min/max column names in the metadata for formats older than "md". * When updating the metadata, reset and disable min/max in the presence of range tombstones (like Cassandra does and until we process them accurately). * Fix the way we maintain min/max column names by: keeping whole clustering key prefixes as min/max rather than calculating min/max independently for each component, like Cassandra does in the "md" format.
