Teiid JON/JOPR/RHQ Console
by Van Halbert
There is currently a jbedsp monitor project that represents the
beginning of the teiid console for configuration and monitoring. It
was was originally developed to work with MetaMatrix 5.5.3 (it was
provided as a tech preview) using JON and its distributed monitoring
architecture. It was later enhanced to work in EMBEDDED JOPR (the
console being delivered with JBoss AS 5), but it was still configured
to work with the old architecture in Teiid. However, the framework
in the jbedsp project is still applicable to developing the next
version to support Teiid embedded and Teiid Server. So I'm
planning on moving it tomorrow, unless something changes.

6.2 M1 update
by Steven Hawkins
Hello All,
Now that we've got the new runtime module in shape, the examples/quick start updated, and encryption changes under control M1 will come out on Monday. There will be a few more check ins over the weekend cleaning up a few things at the connector level, but let a lead know if you have pending changes you want to get in. M2 will be targeted for 8/10 and will at least include the data command pass-through functionality from TEIID-669. The RC should be two weeks after that - please have all feature/enhancement work done at that time. The target release date in JIRA has been updated to 9/14 - Ramesh noticed it was too far out - but it's still a bit longer than 12 weeks given the timing of JBoss World.

Re: [teiid-dev] [teiid-users] sql server time column
by Steven Hawkins
It's not an issue of whether it can be addressed at the connector level (see the response to Larry). It's a question of whether it's appropriate at the connector level.

Is there anyway we can query the SQLServer for how it is basing the
time? If we can, can it be a connector capability?

Re: [teiid-dev] [teiid-users] sql server time column
by Steven Hawkins
There are workarounds that can be done (the previous approach was to change time literals to {ts'1900-01-01 <time>}), but I would rather not do them because:
1. customers are unlikely to have this scenario where a datetime artificially represents only time values - we forced the issue with our bqt testing
2. if you just wrap the column in the appropriate expression at the connector level, you miss out on our rewriter enhancements.

Can this not be done in the connector?

sql server time column
by Steven Hawkins
Several changes in Teiid have made our old behavior of allowing users to mark datatime columns from SQL Server/Sybase as time type in Teiid not work (it used to only fail in some situations with prepared statements). The issue is that SQL Server treats the default year for a time value as 1900 instead of 1970.
My preferred approach is to have users represent the source datetime as a timestamp in Teiid (which is the default upon import), but perform type reconciliation in a virtual model using the following expression - convert(timestampadd(SQL_TSI_YEAR, 70, <source datatime>), time).
To ensure this doesn't harm performance I can add a rewrite rule to perform the inversion of timestampadd.
Since it includes the time type, this isn't an issue with SQL Server 2008.

6.2 M1 update
by Steven Hawkins
Hello all,
Just a few updates. We had a bad build to fix on Friday, so we will shoot for tomorrow for an M1 build. SVN and JIRA mailing lists still seem to be down, but forum mailing lists are back up. The defect list for 6.2 has been shrinking at a good rate and should be in the low thirties by the time we're looking at M2.

Re: [teiid-dev] Teiid Server Kit
by John Doyle
I like teiid-runtime. teiid-engine occurred to me, but I think runtime is better.

Integration Testing
by Van Halbert
Since there is already a teiid-test-integration project, what should
this new integration testing project be called? The current teiid-
test-integration appears its tests are related to testing the sdk.
Maybe we should have a different organization (grouping) of what we're
testing (i.e., driver, sdk, connectors) so we can tell what we have /
find and where to contribute. Maybe create an integration test
project for each (i.e., sdk-test-integration, driver-test-
integration, etc.).
Thoughts / suggestions / comments.

I agree with this as a goal, but I don't think it's going to be possible in this particular case. To the best of my knowledge there is no way to programmatically modify the metadata of a Salesforce app. Views built on top of the physical model of the default free developer Salesforce app are one possible way to to the common schema you're describing. Then the contributor would be able to specify his credentials and that should be enough.
Another limitation of this particular case that probably won't inform the larger framework, but I mention it anyway, is that modifications of the default Salesforce app were made to expose some of their non-standard types for testing that are not used in the default app. So no community user would be able to run all of the Salesforce tests unless they made manual modifications to their default app. This limitation could be clearly specified in the failure messages of the tests depending upon the modification, and it's not a wrinkle that I think we should be spending time on.
But like I said at the top, I agree with the goal you propose.

Re: [teiid-dev] Integration Testing
by John Doyle
Just to make sure I understand this proposal, are we creating and opening a test framework, or a framework + tests?
I ask because I am thinking of how we can test some of the SAS services that I have been working with, SalesForce for now, but Google, Amazon, and Yahoo as well. All of these present similar concerns: we can't mock up the source, we don't want to share the credentials, they can be very slow (due to latency, API limitations, etc).
