StaticSplits is the list of pre-defined split points in the beginning of the keyspace that are there to support separate zone configs for different parts of the system / system config ranges. Exposed publicly so that its ordering can be tested.

Functions

func ObjectIDForKey 

func ObjectIDForKey(key roachpb.RKey) (uint32, bool)

ObjectIDForKey returns the object ID (table or database) for 'key', or (_, false) if not within the structured key space.

func TestingSetDefaultZoneConfig 

func TestingSetDefaultZoneConfig(cfg ZoneConfig) func()

TestingSetDefaultZoneConfig is a testing-only function that changes the default zone config and returns a function that reverts the change.

func TestingSetZoneConfig 

func TestingSetZoneConfig(id uint32, zone ZoneConfig)

func TestingSetupZoneConfigHook 

func TestingSetupZoneConfigHook(stopper *stop.Stopper)

TestingSetupZoneConfigHook initializes the zone config hook to 'testingZoneConfigHook' which uses 'testingZoneConfig'. Settings go back to their previous values when the stopper runs our closer.

type GCPolicy 

type GCPolicy struct {

func (SystemConfig) ComputeSplitKey 

func (s SystemConfig) ComputeSplitKey(startKey, endKey roachpb.RKey) roachpb.RKey

ComputeSplitKey takes a start and end key and returns the first key at which to split the span [start, end). Returns nil if no splits are required.

Splits are required between user tables (i.e. /table/<id>), at the start of the system-config tables (i.e. /table/0), and at certain points within the system ranges that come before the system tables. The system-config range is somewhat special in that it can contain multiple SQL tables (/table/0-/table/<max-system-config-desc>) within a single range.

func (*SystemConfig) Descriptor 

func (*SystemConfig) Descriptor() ([]byte, []int)

func (SystemConfig) Equal 

func (s SystemConfig) Equal(other SystemConfig) bool

func (SystemConfig) GetLargestObjectID 

func (s SystemConfig) GetLargestObjectID(maxID uint32) (uint32, error)

GetLargestObjectID returns the largest object ID found in the config which is less than or equal to maxID. If maxID is 0, returns the largest ID in the config.

GetValue searches the kv list for 'key' and returns its roachpb.Value if found.

func (SystemConfig) GetZoneConfigForKey 

func (s SystemConfig) GetZoneConfigForKey(key roachpb.RKey) (ZoneConfig, error)

GetZoneConfigForKey looks up the zone config for the range containing 'key'. It is the caller's responsibility to ensure that the range does not need to be split.

	// If GC policy is not set, uses the next highest, non-null policy
	// in the zone config hierarchy, up to the default policy if necessary.
	GC GCPolicy `protobuf:"bytes,4,opt,name=gc" json:"gc"`
	// NumReplicas specifies the desired number of replicas
	NumReplicas int32 `protobuf:"varint,5,opt,name=num_replicas,json=numReplicas" json:"num_replicas" yaml:"num_replicas"`
	// Constraints constrains which stores the replicas can be stored on. The
	// order in which the constraints are stored is arbitrary and may change.
