------------------------------------------
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}
