| <div class="block">An action that performs the same operation as <a href="../../../../../org/apache/iceberg/ExpireSnapshots.html" title="interface in org.apache.iceberg"><code>ExpireSnapshots</code></a> but uses |
| Spark to determine the delta in files between the pre and post-expiration table metadata. All of |
| the same restrictions of <a href="../../../../../org/apache/iceberg/ExpireSnapshots.html" title="interface in org.apache.iceberg"><code>ExpireSnapshots</code></a> also apply to this action. |
| |
| <p>This action first leverages <a href="../../../../../org/apache/iceberg/ExpireSnapshots.html" title="interface in org.apache.iceberg"><code>ExpireSnapshots</code></a> to expire snapshots and |
| then uses metadata tables to find files that can be safely deleted. This is done by anti-joining |
| two Datasets that contain all manifest and content files before and after the expiration. The |
| snapshot expiration will be fully committed before any deletes are issued. |
| |
| <p>This operation performs a shuffle so the parallelism can be controlled through |
| 'spark.sql.shuffle.partitions'. |
| |
| <p>Deletes are still performed locally after retrieving the results from the Spark executors.</div> |
