Class Config

java.lang.Object
org.neo4j.driver.Config
All Implemented Interfaces:
Serializable
@Immutable public final class Config extends Object implements Serializable
A configuration class to config driver properties.

To build a simple config with custom logging implementation: 

 
 Config config = Config.builder()
                       .withLogging(new MyLogging())
                       .build();

To build a more complicated config with tuned connection pool options: 

 
 Config config = Config.builder()
                       .withEncryption()
                       .withConnectionTimeout( 10, TimeUnit.SECONDS)
                       .withMaxConnectionLifetime(30, TimeUnit.MINUTES)
                       .withMaxConnectionPoolSize(10)
                       .withConnectionAcquisitionTimeout(20, TimeUnit.SECONDS)
                       .build();
