Julian Hyde commented on CALCITE-5615:
--------------------------------------
If a tool could be used outside of Calcite, then I believe that it should be a
separate project. I followed this philosophy with Quidem, SQLLine, Avatica, and
data projects such as
[scott-data-hsqldb|https://github.com/julianhyde/scott-data-hsqldb]. Because if
the tool is inside a larger project, no one will realize that they can use it
standalone, and over time the projects will inevitably become more coupled.
Another good example is [tpcds-kit|https://github.com/gregrahn/tpcds-kit].
I'll repeat the offer I made above. If you'd like to make this into a project
that deploys artifacts to Maven Central I'd be happy to do the work (create the
template project, import the code, make the first release) and make [~mbudiu]
the co-owner/maintainer.

> Sqllogictest is a program designed to verify that an SQL database engine
> computes correct results by comparing the results to identical queries from
> other SQL database engines.
> https://www.sqlite.org/sqllogictest/doc/trunk/about.wiki
> The nice thing about SLT is that it contains more than 7 million tests. The
> tests only cover the core of SQL, ideally the portable part across all
> engines. They only test integers, doubles, and strings. So they could
> probably be part of the Calcite slow tests.
> The tests should be structured so that any query execution engine can be used.
> I plan to contribute such an implementation if people think it is useful, but
> I haven't yet worked out all the details.
