Gabor Kaszab commented on IMPALA-10153:
---------------------------------------
I figured that the "SHOW TABLE HISTORY" is self explanatory and straightforward
to use but didn't think about the subquery use case you showed above.
Let's then give "SELECT * from table.history" a try and see how complicated it
is to implement.
Thanks for your inputs, [~superdupershant]!

> 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).
