Modifier and Type	Field	Description
static final String	BATCH_STRATEGY	Deprecated. Use BUILDER instead
static final String	BUILDER	Names the BatchBuilder implementation to use.
static final String	ORDER_INSERTS	Enable ordering of entity insert statements by entity type and primary key value, for the purpose of more efficient JDBC batching.
static final String	ORDER_UPDATES	Enable ordering of entity update statements by entity type and primary key value, and of statements relating to collection modification by collection role and foreign key value, for the purpose of more efficient JDBC batching.
static final String	STATEMENT_BATCH_SIZE	Specifies the maximum number of statements to batch together in a stateful session.

Field Details

BUILDER

static final String BUILDER

Names the BatchBuilder implementation to use.

See Also:

• Constant Field Values

Default Value:

Standard builder based on STATEMENT_BATCH_SIZE

STATEMENT_BATCH_SIZE

static final String STATEMENT_BATCH_SIZE

Specifies the maximum number of statements to batch together in a stateful session.

Any positive value enables batching.

This setting has no effect on stateless sessions.

See Also:

• Statement.executeBatch()
• PreparedStatement.addBatch()
• SessionFactoryBuilder.applyJdbcBatchSize(int)
• Constant Field Values

Default Value:

0

ORDER_UPDATES

static final String ORDER_UPDATES

Enable ordering of entity update statements by entity type and primary key value, and of statements relating to collection modification by collection role and foreign key value, for the purpose of more efficient JDBC batching.

The sort order also reduces the chance of a unique key violation when a collection element is moved from one parent to a different parent, by executing collection updates involving removals before collection updates which don't involve removals.

See Also:

• SessionFactoryBuilder.applyOrderingOfUpdates(boolean)
• Constant Field Values

Default Value:

false

ORDER_INSERTS

static final String ORDER_INSERTS

Enable ordering of entity insert statements by entity type and primary key value, for the purpose of more efficient JDBC batching.

The sort order respects foreign key dependencies between entities, and therefore does not increase the chance of a foreign key violation.

See Also:

• SessionFactoryBuilder.applyOrderingOfInserts(boolean)
• Constant Field Values

Default Value:

false

BATCH_STRATEGY

@Deprecated(since="6.4")
static final String BATCH_STRATEGY

Deprecated.

Use BUILDER instead
