<div class="block">An action that performs the same operation as <a href="../../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="../../ExpireSnapshots.html" title="interface in org.apache.iceberg"><code>ExpireSnapshots</code></a> also apply to this action.
<p>
This action first leverages <a href="../../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>
