[JBoss JIRA] (TEIID-3545) Improvements in default handling
by Steven Hawkins (JIRA)
[ https://issues.jboss.org/browse/TEIID-3545?page=com.atlassian.jira.plugin... ]
Steven Hawkins commented on TEIID-3545:
---------------------------------------
Using the default keyword will require either significant parsing changes or a good bit of validation to ensure the expression is not used in other contexts. Also adding support for DEFAULT VALUES seems low priority as it would not be often used.
That leaves:
- allowing the default value to be a Teiid expression (this may require extension metadata for backwards compatibility and some sources use special values)
- allowing the source query to use the source default, rather than using a default specified in Teiid. This will also likely require extension metadata and/or an import option to not set the default value.

> The current default field is just a string value and captured as a string value at import time - in general it should be allowed to be an expression. Also our insert syntax should support the default/defaults keywords and be able to propagate that to the source, rather than using the default on the model.

> With TEIID-3052 we are now fully processing almost all results in the originating procedure scope whereas before we were effective performing pipelining in that the results were created off of the tuple source on demand.
> With some upfront or processing time detection we could see when the processorplan is relying upon resources from the program scope and if not go ahead and pop/return the results as before. We could also develop a better strategy for dealing with the case when resources are needed.

> Key: TEIID-3116
> URL: https://issues.jboss.org/browse/TEIID-3116
> Project: Teiid
> Issue Type: Bug
> Components: Server
> Affects Versions: 8.7.1
> Reporter: Van Halbert
> Assignee: Steven Hawkins
> Priority: Minor
>
> Description of problem:
> Querying a vdb-table which is formed as union of two tables from different datasources. Even though "set partialresultsmode true" is run as initial query, instead of retreiving 0 rows from a datasources that is down, exception is promoted.
> Version-Release number of selected component (if applicable):
> DV 6.1 ER1
> How reproducible:
> Every time
> Steps to Reproduce:
> 1. Define one valid and one invalid datasource(invalid connection-url).
> 2. Create vdb which maps tables from both datasources.
> 3. Set partialresultsmode to true
> 4. Execute query on the given vdb-table
> Actual results:
> TeiidSQLException
> TEIID30498 Remote org.teiid.api.exception.query.QueryPlannerException: TEIID30498 Capabilities for ORBQT were not avaialable. The command could not be planned properly.
> Expected results:
> 0 rows from invalid datasource.

> Perform the server installation steps as part of the build and add the result to the downloads page. It seems like this is something that everyone who isn't using the embedded kit has to do anyways, and would hopefully eliminate confusion caused by people trying to deploy the runtime in unsupported versions of JBoss.
> * Teiid Runtime
> * Teiid Web Console
> * JBoss EAP 6.1 Alpha
> * Resteasy JAX-RS Patch
> End result would simplify the installation process to:
> 1. Unzip Teiid server.
> 2. Run `bin/add-user.sh` script.
> 3. Deploy custom translators, VDB, etc.
