                 Key: SPARK-34978
                 URL: https://issues.apache.org/jira/browse/SPARK-34978
             Project: Spark
          Issue Type: New Feature
          Components: SQL

Some DataSource have the ability to query the older snapshot, like Delta.

The syntax may be like `TIMESTAMP AS OF '

2018-10-18 22:15:12' ` to query the snapshot closest to this time point, or `VERSION AS OF 12` to query the 12th snapshot.
