[jbosstools-dev] Replacement of deprecated teiid runtime client plugins

[phantomjinx]

Afternoon all,

As some of you may know, for Teiid Designer, I have been working over the last few months on a
single teiid-runtime-client plugin that replaces the current 3 (and was soon to be more!)
versioned teiid client plugins. The aims of the single plugin were:

* Forking the teiid codebase and importing as a git submodule was proving unsustainable and fast
becoming unmanagable hence a single plugin contained in (and maintained by Designer devs) was
preferred;

* The plugin should allow Designer to perform local sql parsing, resolving and validation of vdb
models, as well as connecting/deploying/undeploying to all teiid instances at version 7.7+;

* A single plugin where 90% of the teiid client codebase is the same should be able to handle,
with the help of annotations and version checks, the 10% of differences between teiid versions;

* Only where absolutely necessary should actual different classes be created that are teiid
version-specific, eg. Teiid7Parser, Teiid8Parser;

Thus, the single plugin is backward compatible (but then most of teiid is already backward
compatible!) but it should also be forward limiting in that validating teiid v8 sql syntax against
a teiid v7 version should correctly fail.

Currently, the plugin supports up to teiid v8.7.0.CR2 and will support 8.7.0.Final upon its
release. At this point, the plugin is being soak tested and I have now included it in nightly
builds to allow people to play with it / find bugs and otherwise spot whatevers bits I have missed.

Hope that is clear but any questions do not hesitate to ask.

Regards

PGR
