Class TransactionConfig

java.lang.Object

org.neo4j.driver.TransactionConfig

All Implemented Interfaces:

Serializable

public class TransactionConfig
extends Object
implements Serializable

Configuration object containing settings for transactions. Instances are immutable and can be reused for multiple transactions.

Configuration is supported for:

• queries executed in auto-commit transactions - using various overloads of Session.run(String, TransactionConfig) and AsyncSession.runAsync(String, TransactionConfig)
• transactions started by transaction functions - using Session.readTransaction(TransactionWork, TransactionConfig), Session.writeTransaction(TransactionWork, TransactionConfig), AsyncSession.readTransactionAsync(AsyncTransactionWork, TransactionConfig) and AsyncSession.writeTransactionAsync(AsyncTransactionWork, TransactionConfig)
• unmanaged transactions - using Session.beginTransaction(TransactionConfig) and AsyncSession.beginTransactionAsync(TransactionConfig)

Creation of configuration objects can be done using the builder API:

 
 Map<String, Object> metadata = new HashMap<>();
 metadata.put("type", "update user");
 metadata.put("application", "my application");

 TransactionConfig config = TransactionConfig.builder()
                 .withTimeout(Duration.ofSeconds(4))
                 .withMetadata(metadata)
                 .build();
