             Summary: Add support for ALTER TABLE CREATE TAG statement for 
Iceberg tables
                 Key: IMPALA-15528
                 URL: https://issues.apache.org/jira/browse/IMPALA-15528
             Project: IMPALA
          Issue Type: Improvement
            Reporter: Zoltán Borók-Nagy


With ALTER TABLE CREATE TAG, and time-travel based on TAG we could add 
time-travel queries to .test files easily:

{noformat}
CREATE TABLE t ... ICEBERG;

INSERT INTO t ...;

ALTER TABLE t CREATE TAG 'first-snapshot' AS OF NOW();

INSERT INTO t ...;

SELECT * FROM t FOR SYSTEM_VERSION AS OF 'first-snapshot';
{noformat}
