Project: Teiid
Issue Type: Feature Request

Affects Versions: 8.1
Environment: Windows 7 64 bit
Reporter: Anil Allewar
Assignee: Steven Hawkins
It would …
[View More]be to useful allow the installation of custom listeners since we don't have a global vdb table that could have customizable triggers. This could cover for example custom strategies for external materialization initialization.
This would also help in where an application wants to listen to when a VDB was added, made active, destroyed so that it can handle those events as required by the application.

[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 …
[View More]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.
