Interface Summary

Interface	Description
ConfigurableForStOptionsFactory	An interface for options factory that pick up additional parameters from a configuration.
ForStDBOperation	Data access operation to ForStDB.
ForStInnerTable<K,V>	The concept of an abstracted table oriented towards ForStDB, and each ForStInnerTable can be mapped to a ForSt internal State.
ForStMemoryControllerUtils.ForStMemoryFactory	Factory for Write Buffer Manager and Bock Cache.
ForStOptionsFactory	A factory for DBOptions and ColumnFamilyOptions to be passed to the ForStStateBackend.

Class Summary

Class	Description
ContextKey<K>	The composite key which contains some context information, such as keyGroup, etc.
ForStConfigurableOptions	This class contains the configuration options for the ForStStateBackend.
ForStDBGetRequest<K,V>	The Get access request for ForStDB.
ForStDBPutRequest<K,V>	The Put access request for ForStDB.
ForStGeneralMultiGetOperation	The general-purpose multiGet operation implementation for ForStDB, which simulates multiGet by calling the Get API multiple times with multiple threads.
ForStKeyedStateBackend<K>	A KeyedStateBackend that stores its state in ForSt.
ForStKeyedStateBackendBuilder<K>	Builder class for ForStKeyedStateBackend which handles all necessary initializations and cleanups.
ForStMemoryConfiguration	The settings regarding ForSt memory usage.
ForStMemoryControllerUtils	Utils to create Cache and WriteBufferManager which are used to control total memory usage of ForSt.
ForStNativeMetricMonitor	A monitor which pulls {RocksDB} native metrics and forwards them to Flink's metric group.
ForStNativeMetricOptions	Enable which ForSt metrics to forward to Flink's metrics reporter.
ForStOperationUtils	Utils for ForSt Operations.
ForStOptions	Configuration options for the ForStStateBackend.
ForStResourceContainer	The container for ForSt resources, including option factory and shared resource among instances.
ForStStateBackend	A StateBackend that stores its state in a ForSt instance.
ForStStateBackendFactory	A factory that creates an ForStStateBackend from a configuration.
ForStStateExecutor	The StateExecutor implementation which executing batch StateRequests for ForStStateBackend.
ForStStateRequestClassifier	The ForSt StateRequestContainer which can classify the state requests by ForStDB requestType (Get、Put or Iterator).
ForStValueState<K,V>	The InternalValueState implement for ForStDB.
ForStWriteBatchOperation	The writeBatch operation implementation for ForStDB.
