| <div class="block">Specify the use of batch writing to optimize transactions with multiple writes, |
| by default batch writing is not used. |
| Batch writing allows multiple heterogeneous dynamic SQL statements to be sent to the database as a single |
| execution, or multiple homogeneous parameterized SQL statements to be executed as a single batch execution. |
| <p>Note that not all JDBC drivers, or databases support batch writing. |
| |
| <p>JPA persistence property Usage: |
| |
| <p><code>properties.add(PersistenceUnitProperties.BATCH_WRITING, BatchWriting.JDBC);</code> |
| |
| <p>Property values are case-insensitive |
| |
| <ul> |
| <li>JDBC - JDBC batch API's are used (dynamic, or parameterized). |
| <li>Bufferred - dynamic SQL is concatenated into a batch SQL string. |
| <li>Oracle-JDBC - Oracle JDBC batch API's are used (allows row count to be returned for optimistic locking). |
| <li><custom-class> - A custom class that extends the BatchWritingMechanism class. |
