------------------------------------------
Summary: Add expire snapshots functionality for Iceberg tables
Key: IMPALA-11362
URL: https://issues.apache.org/jira/browse/IMPALA-11362
Project: IMPALA
Issue Type: New Feature
Components: Frontend
Reporter: Zoltán Borók-Nagy
We want to support the following table maintenance features:
{noformat}
ALTER TABLE test_table EXECUTE expire_snapshots("older_than", <timestamp-expr>);
ALTER TABLE test_table EXECUTE expire_snapshots("retain_last",
<integer-literal>);
ALTER TABLE test_table EXECUTE expire_snapshots("snapshot_id",
<integer-literal>);
{noformat}
They would invoke the corresponding Iceberg APIs, see:
