Types

type Database

type Database struct {

	// Central lock is required for Set/Delete operations. Could be possible
	// to do key-level locking which would allow update Set operations to not
	// take a global lock, but not doing that for now.
	sync.RWMutex
	// contains filtered or unexported fields
}

Database is the main interface for data storage and access for callers.

func New

func New() *Database

New creates a new Database struct, loads any available data from disk, schedules regular checkpointing, then returns a pointer to the Database indicating it is ready to serve requests.

func (*Database) Delete

func (s *Database) Delete(msg *rpc.Msg)

Delete removes the value for the provided key.

func (*Database) Get

func (s *Database) Get(msg *rpc.Msg) (rpc.ValueType, error)

Get stores returns the value for provided key. If not present in the Database then an error is returned instead.

func (*Database) Set

func (s *Database) Set(msg *rpc.Msg)

Set updates the value for provided key. If not already present the value is silently added.
