Package org.apache.cassandra.io.sstable.format

Class Version

java.lang.Object
org.apache.cassandra.io.sstable.format.Version
public abstract class Version extends Object
A set of feature flags associated with a SSTable format

versions are denoted as [major][minor]. Minor versions must be forward-compatible: new fields are allowed in e.g. the metadata component, but fields can't be removed or have their size changed.

Minor versions were introduced with version "hb" for Cassandra 1.0.3; prior to that, we always incremented the major version.
