Types

type LDBDatabase

type LDBDatabase struct {
	GetTimer       metrics.Timer // Timer for measuring the database get request counts and latencies
	PutTimer       metrics.Timer // Timer for measuring the database put request counts and latencies
	DelTimer       metrics.Timer // Timer for measuring the database delete request counts and latencies
	MissMeter      metrics.Meter // Meter for measuring the missed database get requests
	ReadMeter      metrics.Meter // Meter for measuring the database get request data usage
	WriteMeter     metrics.Meter // Meter for measuring the database put request data usage
	CompTimeMeter  metrics.Meter // Meter for measuring the total time spent in database compaction
	CompReadMeter  metrics.Meter // Meter for measuring the data read during compaction
	CompWriteMeter metrics.Meter // Meter for measuring the data written during compaction
	// contains filtered or unexported fields
}

func NewLDBDatabase

func NewLDBDatabase(file string) (*LDBDatabase, error)

NewLDBDatabase returns a LevelDB wrapped object. LDBDatabase does not persist data by it self but requires a background poller which syncs every X. `Flush` should be called when data needs to be stored and written to disk.

func (*LDBDatabase) Close

func (self *LDBDatabase) Close()

func (*LDBDatabase) Delete

func (self *LDBDatabase) Delete(key []byte) error

Delete deletes the key from the queue and database

func (*LDBDatabase) Flush

func (self *LDBDatabase) Flush() error

Flush flushes out the queue to leveldb

func (*LDBDatabase) Get

func (self *LDBDatabase) Get(key []byte) ([]byte, error)

Get returns the given key if it's present.

func (*LDBDatabase) LDB

func (self *LDBDatabase) LDB() *leveldb.DB

func (*LDBDatabase) NewIterator

func (self *LDBDatabase) NewIterator() iterator.Iterator

func (*LDBDatabase) Put

func (self *LDBDatabase) Put(key []byte, value []byte) error

Put puts the given key / value to the queue

type MemDatabase

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

* This is a test memory database. Do not use for any production it does not get persisted

func NewMemDatabase

func NewMemDatabase() (*MemDatabase, error)

func (*MemDatabase) Close

func (db *MemDatabase) Close()

func (*MemDatabase) Delete

func (db *MemDatabase) Delete(key []byte) error

func (*MemDatabase) Flush

func (db *MemDatabase) Flush() error

func (*MemDatabase) Get

func (db *MemDatabase) Get(key []byte) ([]byte, error)

func (*MemDatabase) LastKnownTD

func (db *MemDatabase) LastKnownTD() []byte

func (*MemDatabase) Print

func (db *MemDatabase) Print()

func (*MemDatabase) Put

func (db *MemDatabase) Put(key []byte, value []byte) error

func (*MemDatabase) Set

func (db *MemDatabase) Set(key []byte, value []byte)
