Class Version

  • public abstract class Version
extends java.lang.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.
