Adding WSDL 2.0 Generation
by Ted Jones
In order to facilitate a REST architecture for our web service model based VDBs ( see TEIIDDES-122 ), we need to enable the HTTP binding spec support that WSDL 2.0 provides. Currently, our web service model generates WSDL 1.1. I would like to keep this behavior and add an option to the VDB web services tab to optionally generate WSDL 2.0. The WSDL 1.1 would still be generated according to the model definition, but we would convert to WSDL 2.0 using an Apache project called Woden . The 2.0 version of the wsdl would then be saved with the VDB. This way there would be no model changes required.
One issue I see here is that we could not re-import the WSDL without modifications to the importer for the web services model. That has always been something we have strived for in the past. Granted, we are not claiming support for WSDL 2.0 importing at this time but if we are generating it, it seems like we should go both ways?
Any thoughts on this approach to WSDL 2.0 generation?
Thanks,
Ted

Re: [teiid-designer-dev] Re: [teiid-dev] 6.1 Release
by John Doyle
I'm a connector developer and this release was not immaterial from my perspective, its an embarrassment. NONE of my stuff works. And just to be clear, this is not because of any defect in Teiid, but because of Designer problems that I identified too late to get fixed.
But you know what, I don't care, it's done. I'm asking about 6.1. What are we going to differently for 6.1 to produce a release that is interesting and meaningful to users. Unless we patch the 6.0.0 Designer, which we don't want to do, you won't be able to use any of my connectors with a 6.0.0 Designer and a 6.1 Teiid either. So we have to get 6.1 Teiid to work with 6.1 Designer as I see it.
I've already stated how I think we should do this, leave Teiid in the unstable bucket until we have validated that Teiid and Designer work together. Then move them both to stable, which is the new 'GA'. How you you all think we should accomplish this?

Re: [teiid-designer-dev] Re: [teiid-dev] 6.1 Release
by John Doyle
I'm not really interested in criticizing the 6.0 release, but I'm interested in learning from it and doing better. I think all future releases of Teiid have to have some tooling that works with it. If it's the previous version of Designer that supports it with the exception of new features X and Y, then I think that's acceptable alternative. If it's the forthcoming alternative tooling, that's fine too. I think it greatly undermines the value of a the release, and is the best way to make a patch release a probability, but it's an improvement. But I think every release has to have tooling that works on the day we release or none of them will matter to users. Can we agree to that?
IMHO, I think we should break the releases apart only when we have the modularity allows us to do it in a verifiable way. Until we have APIs and SPIs that aren't in flux, how will we know and communicate to the community which version of our tools work with which version of Teiid? This seems to me like more work in the long run if we do it without the technical underpinnings already in place. Let's complete the modularization and then cut the cord.
Can you expand on what you mean by "the independent nature of Teiid development"?

Re: [teiid-designer-dev] Re: [teiid-dev] 6.1 Release
by Steven Hawkins
What seems to be disturbing everyone is what the definition of a community release is. Ultimately that's up to the community, so kudos to us for having this discussion. Also, I don't take John's comment below as inflammatory, rather many of you heard me say the same prior to open sourcing that notion of a Teiid only initial release was immaterial from the perspective of most end users (but not connector developers).
In a perfect world with respect to initial community releases, they would have been done at the edge of a productization cycle. Our timing was instead to go open source (or at least make public announcements) in the middle of a development cycle. The 6.0.0 release of Teiid from an product perspective would be a milestone, but was done for the community for two reasons. First it was considered desirable to have a release close to the project announcement date. The other reason, which is more important, was to establish the independent nature of Teiid development. We may not all agree with those points, but there it stands.
To sum up the best parts of this discussion:
Does the Teiid 6.0.0 release matter to most users - Not really.
Will there be synchronization between future Teiid and Teiid Designer releases - Not really.
Will we be in the habit of patch releases - Not really.
Do we need modularize our software more - Yes. A better separation of Teiid Designer's usage of Teiid's code, separating out projects for "large" connectors, soap services, etc.
All need to be explored. We've made the jump from 1 code base to 3, we can do more if needed.

Agreed. That's why I'm pretty much considering Teiid as a whole as
unreleased, regardless of what version the Teiid Server team is
working on. The difficult part is figuring out a way to convey this
effectively to the community. Backing off a little on what I said

Re: [teiid-designer-dev] Re: [teiid-dev] 6.1 Release
by Steven Hawkins
Everyone here is attempting to build a thriving community. It's just that there are differing opinions about how to do it. The major issue is whether Teiid "releases" should be mothballed prior to Designer availability. So far there is no agreement on that. Van's assertion that Teiid or the Server isn't valuable without a Designer release is really is really the same line of thought.
The Teiid lead's perspective is that we need to have defined Teiid releases - in terms of connector api, server api, functionality, etc. - so that the Designer, connector, or server developers have something stable to target. To that end a 6.0.0 release of Teiid does not impede the 6.0 release of Designer, rather it is essential. Whether it's "usable" on its own only matters to how we promote its use. Furthermore all changes made based upon Designer integration problems have been made to both 6.0.1 and 6.1.0. So we will have the ability to provide a release version of Teiid that is completely compatible with the Designer near its release. Finally the Teiid developers have been working constantly with the Designer developers to hammer out all release issues.
I should have also been more particular about the phase "forward looking". I mean to say the 7 release will have alternative metadata mechanisms.

Plain and simple, the server is no good without the designer. And
until we can get thru this period of getting it all to work together
as a stable set of code, it doesn't do anyone any good. I agree,
down the road, once we get this working that the 2 projects can live
independently, but it can't happen until its all working. And the
community doesn't start thriving until they can use it.

I agree with this as long as the predicate is that there is a version of tooling (Designer or other) that we have validated to work with the Teiid release (excepting the new features in the Teiid release as you described above).

The general problem I'm referring to here not truly a Designer dependency, but rather a model dependency. New connector features often expect new modeling constructs that can be difficult for a user to get right. Currently Designer importers are the only solution, but with other tooling that will change.

What about leaving it on the shelf until they're both done? There's no lost time if one project completes it's 6.1 work but it's not 'officially' released and labeled as 6.1 until the other project is ready. We already have stable and unstable slots on the community site, but we're not putting any unstable out there. Put it out there as unstable and move onto features for the next release. When we've reach a level of quality between the two projects, then we label it and post the stable version.

All of these things are great, and I agree with all of these things. To go further, we have wanted and and even produced alternative tooling (mmshell). Someday there may be several different options for creating the artifacts that Teiid needs, and then your argument becomes much stronger. But I don't think the projects should adopt a process that treats the the individual projects as independent when they aren't yet. We should operate in the circumstances that exist, not the ones we hope to create.

Yes, should, but how will we know? How do we validate that? The truth is that we don't know what we're going to be changing in 18 months, and maybe it's going to be disruptive, maybe it's not. I tend to think that if it's not, then we're probably not doing very interesting work. Another uncomfortable truth is that it's very hard to see the full consequences of the changes we make.

Re: [teiid-designer-dev] Re: [teiid-dev] 6.1 Release
by John Doyle
Yes, the consumers of Teiid need something stable to target, but it doesn't have to be released.
By releasing Teiid before the associated project(s)/systems we only create confusion for the community. When we release we're all going to post to our blogs, and a couple of months later a press release will happen (who could resist), and drive traffic to go and get the release. Why set up a system where brand new prospective user who just heard about us for the first time can't come and get version 6.0 of our engine, and 6.0 of our designer, and just assume that they work together? I understand that patches will happen, and we have to manage that, but why set it up that way?
Please explain to me what is the value of a released 6.0 or 6.1 Teiid if there is no tool that works with it?
I don't question that the Teiid team has been working closely with the Designer team, and I don't question that you have a bear of a schedule for 6.1 and forward. I just don't see the point on closing the door on a release with no tooling. Please explain the benefits to me.

Re: [teiid-designer-dev] Re: [teiid-dev] 6.1 Release
by John Doyle
I addressed the desire to have additional mechanisms to create Teiid artifacts, and those mechanisms don't exist yet, we shouldn't operate like they do.
Its our job to build a thriving community, and the success of that effort will be determined by our ability to produce compelling high quality community projects, not platforms. The platform is immaterial to this discussion.

Re: [teiid-designer-dev] Re: [teiid-dev] 6.1 Release
by Steven Hawkins
We understand your perspective, but forward looking we do not see the Designer as being the only metadata mechanism for Teiid. Intrinsically tying the release schedules together even from the start does not seem helpful. I also understand that Designer feels pressure to release - however there is no hard requirement to do so.
As Ramesh indicates it is already the role of the platform release to put the stamp of quality across all correlated projects in that platform. We do not need to reproduce that effort in the community - it will already flow into the upstream.
Also we will have a 6.1.0 release in the unstable spot starting next week.

What about leaving it on the shelf until they're both done? There's no lost time if one project completes it's 6.1 work but it's not 'officially' released and labeled as 6.1 until the other project is ready. We already have stable and unstable slots on the community site, but we're not putting any unstable out there. Put it out there as unstable and move onto features for the next release. When we've reach a level of quality between the two projects, then we label it and post the stable version.

Why do we want to have a process that lends itself to the possibility that we will have to patch a release just so users can have tooling that works with it?

All of these things are great, and I agree with all of these things. To go further, we have wanted and and even produced alternative tooling (mmshell). Someday there may be several different options for creating the artifacts that Teiid needs, and then your argument becomes much stronger. But I don't think the projects should adopt a process that treats the the individual projects as independent when they aren't yet. We should operate in the circumstances that exist, not the ones we hope to create.

Yes, should, but how will we know? How do we validate that? The truth is that we don't know what we're going to be changing in 18 months, and maybe it's going to be disruptive, maybe it's not. I tend to think that if it's not, then we're probably not doing very interesting work. Another uncomfortable truth is that it's very hard to see the full consequences of the changes we make. But either way we should adopt a process that leads to higher quality, and I think that posting the projects as unstable until we validate compatibility achieves that without negative effect.
