Field Detail

FACTORY

public static final String FACTORY

Sets the transaction factory to be used (LocalTransactionFactory for example).

See Also:

Constant Field Values

COMMIT_BEFORE_COMPLETION

public static final String COMMIT_BEFORE_COMPLETION

For transaction factories that uses synchronization, commits the transaction in the beforeCompletion stage. Relevant transaction factories are JTA and Spring.

Can have true or false values, defaults to false.

Must be set when using a jdbc based index, and must not be used in other cases!.

Constant Field Values

MANAGER_LOOKUP

public static final String MANAGER_LOOKUP

TransactionManagerLookup implementor to use for obtaining the TransactionManager

See Also:

Constant Field Values

USER_TRANSACTION

public static final String USER_TRANSACTION

JNDI name of JTA UserTransaction object

See Also:

Constant Field Values

CACHE_USER_TRANSACTION

public static final String CACHE_USER_TRANSACTION

Set whether to cache the JTA UserTransaction object fetched from JNDI.

Default is "true": UserTransaction lookup will only happen at startup, reusing the same UserTransaction handle for all transactions of all threads. This is the most efficient choice for all application servers that provide a shared UserTransaction object (the typical case).

Turn this flag off to enforce a fresh lookup of the UserTransaction for every transaction. This is only necessary for application servers that return a new UserTransaction for every transaction, keeping state tied to the UserTransaction object itself rather than the current thread.

See Also:

Constant Field Values

ISOLATION

public static final String ISOLATION

The transaction isolation, can be one of the 4 constants values.

See Also:

Constant Field Values

ISOLATION_CLASS

public static final String ISOLATION_CLASS

The transaction isolation class name that will be used as the transaction. Overrides the TRANSACTION_ISOLATION if set.

See Also:

Constant Field Values

ISOLATION_NONE

public static final String ISOLATION_NONE

Used as the value for the TRANSACTION_ISOLATION setting. Configures the transaction isolation level to have no support for transactions.

See Also:

Constant Field Values

ISOLATION_READ_UNCOMMITTED

public static final String ISOLATION_READ_UNCOMMITTED

Used as the value for the TRANSACTION_ISOLATION setting. Configures the transaction isolation level to have a read uncommitted support for transactions. Dirty reads, non-repeatable reads and phantom reads can occur.

See Also:

Constant Field Values

ISOLATION_READ_COMMITTED

public static final String ISOLATION_READ_COMMITTED

Used as the value for the TRANSACTION_ISOLATION setting. Configures the transaction isolation level to have a read committed support for transactions. Dirty reads are prevented, non-repeatable reads and phantom reads can occur.

See Also:

Constant Field Values

ISOLATION_REPEATABLE_READ

public static final String ISOLATION_REPEATABLE_READ

Used as the value for the TRANSACTION_ISOLATION setting. Configures the transaction isolation level to have a repeatable read support for transactions. Dirty reads and non-repeatable reads are prevented, phantom reads can occur.

See Also:

Constant Field Values

ISOLATION_SERIALIZABLE

public static final String ISOLATION_SERIALIZABLE

Used as the value for the TRANSACTION_ISOLATION setting. Configures the transaction isolation level to have a serializable support for transactions. Dirty reads, non-repeatable reads and phantom reads are prevented.

See Also:

Constant Field Values

ISOLATION_BATCH_INSERT

public static final String ISOLATION_BATCH_INSERT

Deprecated. Use LUCENE transaction isolation instead, defaults to it

See Also:

Constant Field Values

ISOLATION_LUCENE

public static final String ISOLATION_LUCENE

Used as the value for the TRANSACTION_ISOLATION setting. Configures the transaction isolation level to have a lucene isolation level allowing for fast Create/Update/Delete operations whild read/search operations won't "see" the operations done during the transaction.

See Also:

Constant Field Values

DISABLE_AUTO_JOIN_SESSION

public static final String DISABLE_AUTO_JOIN_SESSION

When opening a session, Compass tries to automatically start a transaction and join it. This might mean that transaction settings when running within a managed environemnt won't take affect. The settings allows to disable the auto joining of a session to a transaction.

See Also:

Constant Field Values

DISABLE_THREAD_BOUND_LOCAL_TRANSATION

public static final String DISABLE_THREAD_BOUND_LOCAL_TRANSATION

This settings allows to disable the default behaviour of the Local transaction factory to bind the session / transaction to the local thread. This means that each call to beginTransaction will create a new transaction and not join one if one is already in progress within the thread.

See Also:

Constant Field Values

TRANSACTION_TIMEOUT

public static final String TRANSACTION_TIMEOUT

Configures the transaction timeout (JTA or Spring). The defualt is -1 which does not set the timout and uses the default one configured for the transaction manager.

Constant Field Values
