             Summary: Allow dot(.) in database path component
                 Key: IMPALA-14914
                 URL: https://issues.apache.org/jira/browse/IMPALA-14914
             Project: IMPALA
          Issue Type: Bug
          Components: Catalog, Frontend
            Reporter: Zoltán Borók-Nagy


Allow dot(.) in database path component (if it is quoted). Dots can appear in Iceberg REST namespaces.

In catalog federation context it is also possible that catalog information (of the underlying/federated catalogs) is encoded in the database name, e.g. the root REST catalog returns the following top-level namespaces:
* catalog_a.db1
* catalog_b.db1
* catalog_c.db2

To query tables in such catalogs, the user could write:

{noformat}
SELECT * FROM `catalog_b.db1`.my_tbl;
{noformat}
