  - getTxTimeoutOnPartitionMapExchange
```
public long getTxTimeoutOnPartitionMapExchange()
```
    Some Ignite operations provoke partition map exchange process within Ignite to ensure the partitions distribution state is synchronized cluster-wide. Topology update events and a start of a new distributed cache are examples of those operations.
    When the partition map exchange starts, Ignite acquires a global lock at a particular stage. The lock can't be obtained until pending transactions are running in parallel. If there is a transaction that runs for a while, then it will prevent the partition map exchange process from the start freezing some operations such as a new node join process.
    This property allows to rollback such long transactions to let Ignite acquire the lock faster and initiate the partition map exchange process. The timeout is enforced only at the time of the partition map exchange process.
    0 means transactions will never be rolled back on partition map exchange.
    Default value is TX_TIMEOUT_ON_PARTITION_MAP_EXCHANGE.
    
    Returns:
    
    Transaction timeout for partition map synchronization in milliseconds.
  - setTxTimeoutOnPartitionMapExchange
```
public TransactionConfiguration setTxTimeoutOnPartitionMapExchange(long txTimeoutOnPartitionMapExchange)
```
    Sets transaction timeout on partition map exchange. 0 means transactions will never be rolled back on partition map exchange.
    
    Parameters:
    
    txTimeoutOnPartitionMapExchange - Transaction timeout value in milliseconds.
    
    Returns:
    
    this for chaining.
  - getDeadlockTimeout
```
public long getDeadlockTimeout()
```
    This is an experimental feature. Transactional SQL is currently in a beta status.
    Transaction deadlocks occurred for caches configured with CacheAtomicityMode.TRANSACTIONAL_SNAPSHOT can be resolved automatically.
    Deadlock detection starts when one transaction is waiting for an entry lock more than a timeout specified by this property.
    Timeout is specified in milliseconds and 0 means that automatic deadlock detection is disabled. Default value is defined by DFLT_DEADLOCK_TIMEOUT.
    
    Returns:
    
    Timeout before starting deadlock detection.
  - setDeadlockTimeout
```
public TransactionConfiguration setDeadlockTimeout(long deadlockTimeout)
```
    This is an experimental feature. Transactional SQL is currently in a beta status.
    Sets a timeout before starting deadlock detection for caches configured with CacheAtomicityMode.TRANSACTIONAL_SNAPSHOT.
    Timeout is specified in milliseconds and 0 means that automatic deadlock detection is disabled. Default value is defined by DFLT_DEADLOCK_TIMEOUT.
    
    Parameters:
    
    deadlockTimeout - Timeout value in milliseconds.
    
    Returns:
    
    this for chaining.
  - getPessimisticTxLogSize
```
public int getPessimisticTxLogSize()
```
    Gets size of pessimistic transactions log stored on node in order to recover transaction commit if originating node has left grid before it has sent all messages to transaction nodes.
    If not set, default value is 0 which means unlimited log size.

    Pessimistic transaction log size.

public <T> TransactionConfiguration setTxManagerFactory(javax.cache.configuration.Factory<T> factory)
```
    Sets transaction manager factory for available javax.transaction.TransactionManager implementation, if any.
    It allows to use different transactional systems. Implement factory that produce native javax.transaction.TransactionManager within your environment.
    The following implementations are provided out of the box (jta module must be enabled):
    - org.apache.ignite.cache.jta.jndi.CacheJndiTmFactory utilizes configured JNDI names to look up a transaction manager.
    - org.apache.ignite.cache.jta.websphere.WebSphereTmFactory an implementation of Transaction Manager factory to be used within WebSphere Application Server.
    - org.apache.ignite.cache.jta.websphere.WebSphereLibertyTmFactory an implementation of Transaction Manager factory to be used within WebSphere Liberty.
    Ignite will throw IgniteCheckedException if Factory.create() method throws any exception, returns null-value or returns non-TransactionManager instance.
    Type Parameters:
    
    T - Instance of javax.transaction.TransactionManager.
    
    Parameters:
    
    factory - Transaction manager factory.
    
    Returns:
    
    this for chaining.

    setUseJtaSynchronization(boolean)
  - isUseJtaSynchronization
```
public boolean isUseJtaSynchronization()
```
    Returns:

    See Also:
    
    getTxManagerFactory()
  - setUseJtaSynchronization
```
public TransactionConfiguration setUseJtaSynchronization(boolean useJtaSync)
```
    Sets the flag that defines whether to use lightweight JTA synchronization callback to enlist into JTA transaction instead of creating a separate XA resource. In some cases this can give performance improvement, but keep in mind that most of the transaction managers do not allow to add more that one callback to a single transaction.
    
    Parameters:
    
    useJtaSync - Whether to use JTA javax.transaction.Synchronization instead of javax.transaction.xa.XAResource.
    
    Returns:
    
    this for chaining.
