Types ¶
type ExposedClusterVersion ¶
type ExposedClusterVersion struct {
// contains filtered or unexported fields
}
ExposedClusterVersion manages the active version of a running node.
func NewDefaultExposedClusterVersion ¶
func NewDefaultExposedClusterVersion(engines []engine.Engine) *ExposedClusterVersion
NewDefaultExposedClusterVersion returns an *ExposedClusterVersion which takes its updates from the global version cluster setting.
func NewExposedClusterVersion ¶
func NewExposedClusterVersion( getter func() base.ClusterVersion, engines []engine.Engine, ) *ExposedClusterVersion
NewExposedClusterVersion initializes an ExposedClusterVersion which takes into account the gossiped cluster version (if any) and the cluster version (if any) persisted on the given engines, and updates the engines as the cluster-wide version is bumped before exposing these new versions.
While this variable might hold a stale value (owing to the fact that the source of truth may not be local to the node), the MinimumVersion represented by it does not decrease.
func (*ExposedClusterVersion) IsActive ¶
func (ecv *ExposedClusterVersion) IsActive(v roachpb.Version) bool
IsActive returns true if the features of the supplied version are active at the running version.
func (*ExposedClusterVersion) Version ¶
func (ecv *ExposedClusterVersion) Version() base.ClusterVersion
Version returns the minimum cluster version the caller may assume is in effect.
