Grant Henke updated IMPALA-9773:
--------------------------------
    Description: 
Kudu has the concept of snapshot scans which can be used to query the state of 
a table at some point in the past (up to 7 days by default). To date it is used 
for read consistency and backup and restore, but it can also be naturally 
leveraged to "time travel" and query table at some time in the past.

A WIP patch adding a the `AS OF` syntax to Kudu queries can be found here:

[https://gerrit.cloudera.org/#/c/13342/]
