| <div class="block">Enables validation that delete files added concurrently do not conflict with this commit's operation. |
| <p> |
| This method must be called when the table is queried to produce a row delta for UPDATE and |
| MERGE operations independently of the isolation level. Calling this method isn't required |
| for DELETE operations as it is OK to delete a record that is also deleted concurrently. |
| <p> |
| Validation uses the conflict detection filter passed to <a href="../../../org/apache/iceberg/RowDelta.html#conflictDetectionFilter-org.apache.iceberg.expressions.Expression-"><code>conflictDetectionFilter(Expression)</code></a> and |
| applies to operations that happened after the snapshot passed to <a href="../../../org/apache/iceberg/RowDelta.html#validateFromSnapshot-long-"><code>validateFromSnapshot(long)</code></a>.</div> |
