Documentation

Overview

Package datastore is an internal package containing implementation types for the SDK's data store implementations (in-memory vs. cached persistent store) and related functionality. These types are not visible from outside of the SDK.

This does not include implementations of specific database integrations such as Redis. Those are implemented in separate repositories such as https://github.com/launchdarkly/go-server-sdk-redis-redigo.

Functions

func NewDataStoreEvaluatorDataProviderImpl

func NewDataStoreEvaluatorDataProviderImpl(store interfaces.DataStore, loggers ldlog.Loggers) ldeval.DataProvider

NewDataStoreEvaluatorDataProviderImpl creates the internal implementation of the adapter that connects the Evaluator (from go-server-sdk-evaluation) with the data store.

func NewDataStoreStatusProviderImpl

func NewDataStoreStatusProviderImpl(
	store interfaces.DataStore,
	dataStoreUpdates *DataStoreUpdatesImpl,
) interfaces.DataStoreStatusProvider

NewDataStoreStatusProviderImpl creates the internal implementation of DataStoreStatusProvider.

func NewInMemoryDataStore

func NewInMemoryDataStore(loggers ldlog.Loggers) interfaces.DataStore

NewInMemoryDataStore creates an instance of the in-memory data store. This is not part of the public API; it is always called through ldcomponents.inMemoryDataStore().

func NewPersistentDataStoreWrapper

func NewPersistentDataStoreWrapper(
	core intf.PersistentDataStore,
	dataStoreUpdates intf.DataStoreUpdates,
	cacheTTL time.Duration,
	loggers ldlog.Loggers,
) intf.DataStore

NewPersistentDataStoreWrapper creates the implementation of DataStore that we use for all persistent data stores. This is not visible in the public API; it is always called through ldcomponents.PersistentDataStore().

Types

type DataStoreUpdatesImpl

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

DataStoreUpdatesImpl is the internal implementation of DataStoreUpdates. It is exported because the actual implementation type, rather than the interface, is required as a dependency of other SDK components.

func NewDataStoreUpdatesImpl

func NewDataStoreUpdatesImpl(broadcaster *internal.DataStoreStatusBroadcaster) *DataStoreUpdatesImpl

NewDataStoreUpdatesImpl creates the internal implementation of DataStoreUpdates.

func (*DataStoreUpdatesImpl) UpdateStatus

func (d *DataStoreUpdatesImpl) UpdateStatus(newStatus interfaces.DataStoreStatus)

UpdateStatus is called from the data store to push a status update.
