[JBoss JIRA] Created: (TEIID-669) Support "pass though" SQL commands to sources

Support "pass though" SQL commands to sources
---------------------------------------------
Key: TEIID-669
URL: https://jira.jboss.org/jira/browse/TEIID-669
Project: Teiid
Issue Type: Feature Request
Components: Query Engine
Reporter: Ramesh Reddy
Assignee: Steven Hawkins
Fix For: 6.2.0
Currently there is no mechanism in Teiid, when a query is submitted to a runtime engine that is passed through the query engine unadulterated and unmodified and submitted directly to a source connector. All queries are parsed, optimized, re-written. Some times this limits the functionality in Teiid, when a user would like to execute a query that is very "source" specific. For example Oracle supports lots of Oracle specific functions that are not supported by the SQL spec, to support execution of these in Teiid user need to resort to UDF, which is cumbersome and involves modelling.
Another benefit of this is also to pass DDL to sources, currently since Teiid does not support DDL, this is not possible at all.
There is no-expectation that these queries are part of any data integration, these are one off queries that enhance user experience with Teiid if they use this feature. Command Payload mechanism is similar system that is used for authentication and authorization needs at the connector level, this feature can use similar techniques or use some custom extension to the language to define a query etc.

[JBoss JIRA] Created: (TEIID-1070) Create Amazon SimpleDB Connector
by John Doyle (JIRA)
Create Amazon SimpleDB Connector
---------------------------------
Key: TEIID-1070
URL: https://jira.jboss.org/jira/browse/TEIID-1070
Project: Teiid
Issue Type: Feature Request
Components: Misc. Connectors
Reporter: John Doyle
Assignee: John Doyle
Fix For: 7.1
We need connectivity to Amazon SimpleDB. This should be accomplished through a dedicated connector.
Simple DB presents a few challenges as a Teiid source as it is more like a spreadsheet than a database. Simple DB "Domains' are like individual worksheets and contain any number of items. Items however can have any number of attributes, and the attributes do not have to be the same for ever item. So in a single Domain you can have an item with the attributes Size and Color, and another item with the attributes Color and ExpirationDate. This presents both modeling issues and SQL execution issues. None of them are insurmountable, but users will have to understand the issues and design their integration around them.
