[teiid-issues] [JBoss JIRA] Commented: (TEIID-685) Define Metadata aware Connector API

John Doyle commented on TEIID-685:
----------------------------------
I agree with Ramesh that it's better to move towards the domain objects of tables and
columns, I think this leads to a better API.
I also don't see the need to hide these objects behind interfaces now. I would prefer
us to try and define a common interface layer from this API and the implementations that
are built on top of the forthcoming serialized metadata representation.
Define Metadata aware Connector API
-----------------------------------
Key: TEIID-685
URL: https://jira.jboss.org/jira/browse/TEIID-685
Project: Teiid
Issue Type: Sub-task
Components: Connector API
Reporter: Ramesh Reddy
Assignee: Steven Hawkins
Priority: Critical
Fix For: 6.2.0
Connector API needs to be extended, such that a connector can selectively implement an
interface with which it can expose the metadata of the connector. This is similar to the
concept of JDBC drivers exposing the metadata of the sources they are connected to.
At a minimum, this API must expose all the available
- Tables, with corresponding elements
- Procedures with corresponding parameters
in the data source. There should also be a way to define user defined properties on all
the objects, that can used by tools as they fit.
Please comment, if there are any specific features you would like this to extend, as PK,
FK, Unique keys, indexes etc. Overtime, it is expectation that this will be grown to full
blown metadata store API as the teiid-metadata project.
