}

func (s *ConfigEntryLinkIndex) PrefixFromArgs(args ...interface{}) ([]byte, error)

type Delay 

type Delay struct {
	// contains filtered or unexported fields
}

Delay is used to mark certain locks as unacquirable. When a lock is forcefully released (failing health check, destroyed session, etc.), it is subject to the LockDelay imposed by the session. This prevents another session from acquiring the lock for some period of time as a protection against split-brains. This is inspired by the lock-delay in Chubby. Because this relies on wall-time, we cannot assume all peers perceive time as flowing uniformly. This means KVSLock MUST ignore lockDelay, since the lockDelay may have expired on the leader, but not on the follower. Rejecting the lock could result in inconsistencies in the FSMs due to the rate time progresses. Instead, only the opinion of the leader is respected, and the Raft log is never questioned.

func NewDelay 

func NewDelay() *Delay

NewDelay returns a new delay manager.

func (*Delay) GetExpiration 

func (d *Delay) GetExpiration(key string, entMeta *structs.EnterpriseMeta) time.Time

GetExpiration returns the expiration time of a key lock delay. This must be checked on the leader node, and not in KVSLock due to the variability of clocks.

func (*Delay) SetExpiration 

func (d *Delay) SetExpiration(key string, now time.Time, delay time.Duration, entMeta *structs.EnterpriseMeta)

SetExpiration sets the expiration time for the lock delay to the given delay from the given now time.

type Graveyard 

type Graveyard struct {
	// contains filtered or unexported fields
}

Graveyard manages a set of tombstones.

func NewGraveyard 

func NewGraveyard(gc *TombstoneGC) *Graveyard

func (g *Graveyard) GetMaxIndexTxn(tx *memdb.Txn, prefix string, entMeta *structs.EnterpriseMeta) (uint64, error)

GetMaxIndexTxn returns the highest index tombstone whose key matches the given context, using a prefix match.

func (*Graveyard) InsertTxn 

func (g *Graveyard) InsertTxn(tx *memdb.Txn, key string, idx uint64, entMeta *structs.EnterpriseMeta) error

InsertTxn adds a new tombstone.

func (*Graveyard) ReapTxn 

func (g *Graveyard) ReapTxn(tx *memdb.Txn, idx uint64) error

ReapTxn cleans out all tombstones whose index values are less than or equal to the given idx. This prevents unbounded storage growth of the tombstones.

func (*IndexConnectService) FromArgs added in v1.2.0 

func (idx *IndexConnectService) FromArgs(args ...interface{}) ([]byte, error)

func (*IndexConnectService) FromObject added in v1.2.0

	Key   string
	Value uint64
}

IndexEntry keeps a record of the last index per-table.

type IndexServiceKind added in v1.6.0 

type IndexServiceKind struct{}

IndexServiceKind indexes a *struct.ServiceNode for querying by the services kind. We need a custom indexer because of the default kind being the empty string. The StringFieldIndex in memdb seems to treate the empty string as missing and doesn't work correctly when we actually want to index ""

func (*IndexServiceKind) FromArgs added in v1.6.0 

func (idx *IndexServiceKind) FromArgs(args ...interface{}) ([]byte, error)

func (*IndexServiceKind) FromObject added in v1.6.0

type PreparedQueryIndex struct {
}

func (*PreparedQueryIndex) FromArgs 

func (p *PreparedQueryIndex) FromArgs(args ...interface{}) ([]byte, error)

FromArgs is used when querying for an exact match. Since we don't add any suffix we can just call the prefix version.

func (*PreparedQueryIndex) FromObject 

func (*PreparedQueryIndex) FromObject(obj interface{}) (bool, []byte, error)

}

Tombstone is the internal type used to track tombstones.

type TombstoneGC 

type TombstoneGC struct {
	sync.Mutex
	// contains filtered or unexported fields
}

TombstoneGC is used to track creation of tombstones so that they can be garbage collected after their TTL expires. The tombstones allow queries to provide monotonic index values within the TTL window. The GC is used to prevent monotonic growth in storage usage. This is a trade off between the length of the TTL and the storage overhead.

In practice, this is required to fix the issue of delete visibility. When data is deleted from the KV store, the "latest" row can go backwards if the newest row is removed. The tombstones provide a way to ensure time doesn't move backwards within some interval.
