> 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:
