Batch (Hibernate Javadocs)

All Known Implementing Classes:

BatchImpl
```
@Incubating
public interface Batch
```
Represents a batch of statements to be executed together.
Unlike in JDBC, here we add the ability to batch together multiple statements at a time. In the underlying JDBC this correlates to multiple PreparedStatement objects, one for each DML string, all maintained within the batch.
A batch is usually associated with a JdbcCoordinator.

JdbcCoordinator.getBatch(BatchKey, Integer, Supplier)

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`addObserver(BatchObserver observer)`	Adds an observer to this batch.
`void`	`addToBatch(JdbcValueBindings jdbcValueBindings, TableInclusionChecker inclusionChecker)`	Apply the value bindings to the batch JDBC statements and indicates completion of the current part of the batch.
`void`	`execute()`	Execute this batch.
`BatchKey`	`getKey()`	Retrieves the object being used to key (uniquely identify) this batch.
`PreparedStatementGroup`	`getStatementGroup()`
`void`	`release()`	Used to indicate that the batch instance is no longer needed and that, therefore, it can release its resources.
