Types ¶
type Datastore ¶
func NewDatastore ¶
NewDatastore creates a new badger datastore.
DO NOT set the Dir and/or ValuePath fields of opt, they will be set for you.
func (*Datastore) Batch ¶
Batch creats a new Batch object. This provides a way to do many writes, when there may be too many to fit into a single transaction.
func (*Datastore) CollectGarbage ¶
func (*Datastore) DiskUsage ¶
DiskUsage implements the PersistentDatastore interface. It returns the sum of lsm and value log files sizes in bytes.
func (*Datastore) GetExpiration ¶
func (*Datastore) NewTransaction ¶
NewTransaction starts a new transaction. The resulting transaction object can be mutated without incurring changes to the underlying Datastore until the transaction is Committed.
func (*Datastore) PutWithTTL ¶
type Options ¶
type Options struct { // Please refer to the Badger docs to see what this is for GcDiscardRatio float64 // Interval between GC cycles // // If zero, the datastore will perform no automatic garbage collection. GcInterval time.Duration // Sleep time between rounds of a single GC cycle. // // If zero, the datastore will only perform one round of GC per // GcInterval. GcSleep time.Duration badger.Options }
Options are the badger datastore options, reexported here for convenience.
var DefaultOptions Options
DefaultOptions are the default options for the badger datastore.
