Class DataSystemConfiguration

java.lang.Object

com.launchdarkly.sdk.server.subsystems.DataSystemConfiguration

public final class DataSystemConfiguration
extends java.lang.Object

Configuration for the SDK's data acquisition and storage strategy.

This class is not stable, and not subject to any backwards compatibility guarantees or semantic versioning. It is in early access. If you want access to this feature please join the EAP. https://launchdarkly.com/docs/sdk/features/data-saving-mode

Applications should use DataSystemBuilder or DataSystemModes to create instances of this class, rather than calling the constructor directly.

Constructor Detail

DataSystemConfiguration

public DataSystemConfiguration(com.google.common.collect.ImmutableList<DataSourceBuilder<Initializer>> initializers,
                               com.google.common.collect.ImmutableList<DataSourceBuilder<Synchronizer>> synchronizers,
                               ComponentConfigurer<DataSource> fDv1FallbackSynchronizer,
                               ComponentConfigurer<DataStore> persistentStore,
                               DataSystemConfiguration.DataStoreMode persistentDataStoreMode)

Creates an instance.

This constructor is internal and should not be called by application code.

Parameters:

initializers - see getInitializers()

synchronizers - see getSynchronizers()

fDv1FallbackSynchronizer - see getFDv1FallbackSynchronizer()

persistentStore - see getPersistentStore()

persistentDataStoreMode - see getPersistentDataStoreMode()

Method Detail

getInitializers

public com.google.common.collect.ImmutableList<DataSourceBuilder<Initializer>> getInitializers()

A list of factories for creating initializers for initialization.

Returns:

the list of initializer configurers

getSynchronizers

public com.google.common.collect.ImmutableList<DataSourceBuilder<Synchronizer>> getSynchronizers()

A list of factories for creating synchronizers for synchronization.

Returns:

the list of synchronizer configurers

getFDv1FallbackSynchronizer

public ComponentConfigurer<DataSource> getFDv1FallbackSynchronizer()

A synchronizer to fall back to when FDv1 fallback has been requested.

Returns:

the FDv1 fallback synchronizer configurer, or null

getPersistentStore

public ComponentConfigurer<DataStore> getPersistentStore()

An optional factory for creating a persistent data store. This is optional, and if no persistent store is configured, it will be null.

The persistent store itself will implement PersistentDataStore, but we expect that to be wrapped by a factory which can operate at the DataStore level.

Returns:

the persistent store configurer, or null

getPersistentDataStoreMode

public DataSystemConfiguration.DataStoreMode getPersistentDataStoreMode()

The mode of operation for the persistent data store.

Returns:

the persistent data store mode
