Shant Hovsepian commented on IMPALA-10153:
------------------------------------------

[~gaborkaszab] yes it looked tricky. One thing I'd consider is doing a quick 
survey or design doc just so we don't invent another slightly different syntax.

For example Delta with SparkSQL uses "DESCRIBE HISTORY" 
[https://docs.delta.io/latest/delta-utility.html#describe-history]

Iceberg in SparkSQL uses select * from table.history.

Iceberg with Presto is using a special string in the in the identifier instead 
of overloading the path/dot ( '.' ) qualifier select * from 'table.history' 
[https://github.com/prestosql/presto/blob/master/presto-iceberg/README.md#rolling-back-to-a-previous-snapshot]

It would be nice to have some consistent syntax and functionality.

> Iceberg tables support snapshots/data versioning/time travel.
> It means we can query an older version of the table.
> Probably we'll need to extend Impala's SQL syntax to support such queries 
> (Hive will also support such queries, so we should use the same syntax).
