Types ¶
type Version ¶
type Version struct {
// contains filtered or unexported fields
}
Version represents a Cassandra database server version. Cassandra does not adhere to semver. A Cassandra version string may omit the patch version. In Navigator we query the version of the running Cassandra service via the JMX interface. It is returned as a string via: StorageService.getReleaseVersion: https://github.com/apache/cassandra/blob/cassandra-3.11.2/src/java/org/apache/cassandra/service/StorageService.java#L2863 FBUtilities.getReleaseVersionString: https://github.com/apache/cassandra/blob/cassandra-3.11.2/src/java/org/apache/cassandra/utils/FBUtilities.java#L326 Which appears to read the version string from a `Properties` API which appears to be created via this XML file: https://github.com/apache/cassandra/blob/cassandra-3.11.2/build.xml#L790 Internally, Cassandra converts the version string to a `CassandraVersion` object which supports rich comparison. See https://github.com/apache/cassandra/blob/cassandra-3.11.2/src/java/org/apache/cassandra/utils/CassandraVersion.java In Navigator we parse the Cassandra version string as early as possible, into a similar Cassandra Version object. This also fixes the missing Patch number and stores the version internally as a semver. It also keeps a reference to the original version string so that we can report that in our API. So that the version reported in our API matches the version that an administrator expects.

func (Version) DeepCopy ¶
DeepCopy returns a deep-copy of the Version value. If the underlying semver is a nil pointer, assume that the zero value is being copied, and return that.
