> it would be great to have some kind of test dataset support; currently there is the {{q_test_init.sql}}
which is quite large; and I'm often override it with an invalid string; because I write independent
qtests most of the time - and the load of {{src}} and other tables are just a waste of time
for me ; not to mention that the loading of those tables may also trigger breakpoints - which
is a bit annoying.
> Most of the tests are "only" using the {{src}} table and possibly 2 others; however the
main init script contains a bunch of tables - meanwhile there are quite few other tests which
could possibly also benefit from a more general feature; for example the creation of {{bucket_small}}
is present in 20 q files.
> the proposal would be to enable the qfiles to be annotated with metadata like datasets:
> {code}
> --! qt:dataset:src,bucket_small
> {code}
> proposal for storing a dataset:
> * the loader script would be at: {{data/datasets/__NAME__/load.hive.sql}}
> * the table data could be stored under that location
> a draft about this; and other qfiles related ideas:
