Class RocksDBConfigurableOptions

java.lang.Object

org.apache.flink.contrib.streaming.state.RocksDBConfigurableOptions

All Implemented Interfaces:

Serializable

public class RocksDBConfigurableOptions
extends Object
implements Serializable

This class contains the configuration options for the DefaultConfigurableOptionsFactory.

If nothing specified, RocksDB's options would be configured by PredefinedOptions and user-defined RocksDBOptionsFactory.

If some options has been specifically configured, a corresponding DefaultConfigurableOptionsFactory would be created and applied on top of PredefinedOptions except if a user-defined RocksDBOptionsFactory overrides it.
