I'm new to kudu.
As describe in document, kudu is a column oriented storage engine, and it support sql query when integrated with impala.
My question is that: is impala sql syntax fully support when querying kudu via impala sql?
e.g. is SQL-92 fully support while querying kudu ?
Any answer will be appreciated.

For the most part, tables backed by Kudu can use the same SQL-features as other table types in queries. The biggest differences are in DDL and column type support. You can find a full list of the differences in the known limitations section of the Impala and Kudu documentation.
