| abstraction allows you to use a declarative transaction management to concentrate on business logic rather than |
| transaction life-cycle.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Apache Ignite provides the <code>ignite-spring-tx-ext</code> extension that allows to manage |
| <a href="https://ignite.apache.org/docs/latest/key-value-api/transactions#performing-transactions" target="_blank" rel="noopener">Apache Ignite Transactions</a> |
| through the Spring Transactions abstraction. The mentioned above integration is achieved by providing implementations of the |
| <code>TransactionManager</code> Spring Transactions interface. There are two such implementations: <code>SpringTransactionManager</code> and |
| <code>IgniteClientSpringTransactionManager</code>, which use either Apache Ignite node or Apache Ignite thin client to connect to the |
| Apache Ignite cluster and manage the Apache Ignite transactions.</p> |
| </div> |
| <div class="paragraph"> |
| <p>To enable declarative transaction management in your Spring application, create and configure |
| <code>SpringTransactionManager</code> or <code>IgniteClientSpringTransactionManager</code> bean in the Spring application context. The choice |
| of implementation depends on your preferable way to access the Apache Ignite cluster.</p> |
