- Method Detail
  - configure
```
StateBackend configure(org.apache.flink.configuration.ReadableConfig config,
                       ClassLoader classLoader)
                throws org.apache.flink.configuration.IllegalConfigurationException
```
    Creates a variant of the state backend that applies additional configuration parameters.
    Settings that were directly done on the original state backend object in the application program typically have precedence over setting picked up from the configuration.
    If no configuration is applied, or if the method directly applies configuration values to the (mutable) state backend object, this method may return the original state backend object. Otherwise it typically returns a modified copy.
    
    Parameters:
    
    config - The configuration to pick the values from.
    
    classLoader - The class loader that should be used to load the state backend.
    
    Returns:
    
    A reconfigured state backend.
    
    Throws:
    
    org.apache.flink.configuration.IllegalConfigurationException - Thrown if the configuration contained invalid entries.
