Functions ¶

func New ¶

func New(endpoints []string, options *store.Config) (store.Store, error)

New opens a new BoltDB connection to the specified path and bucket

Types ¶

type BoltDB ¶

type BoltDB struct {

	// By default libkv opens and closes the bolt DB connection  for every
	// get/put operation. This allows multiple apps to use a Bolt DB at the
	// same time.
	// PersistConnection flag provides an option to override ths behavior.
	// ie: open the connection in New and use it till Close is called.
	PersistConnection bool
	// contains filtered or unexported fields
}

BoltDB type implements the Store interface

func (*BoltDB) AtomicDelete ¶

func (b *BoltDB) AtomicDelete(key string, previous *store.KVPair) error

AtomicDelete deletes a value at "key" if the key has not been modified in the meantime, throws an error if this is the case

func (*BoltDB) AtomicPut ¶

func (b *BoltDB) AtomicPut(key string, value []byte, previous *store.KVPair) (*store.KVPair, error)

AtomicPut puts a value at "key" if the key has not been modified since the last Put, throws an error if this is the case

func (*BoltDB) Close ¶

func (b *BoltDB) Close()

Close the db connection to the BoltDB

func (*BoltDB) Exists ¶

func (b *BoltDB) Exists(key string) (bool, error)

Exists checks if the key exists inside the store

func (*BoltDB) List ¶

func (b *BoltDB) List(keyPrefix string) ([]*store.KVPair, error)

List returns the range of keys starting with the passed in prefix

func (*BoltDB) Put ¶

func (b *BoltDB) Put(key string, value []byte) error

Put the key, value pair. index number metadata is prepended to the value
