It's nice that q has caching.... then again, it kind of needs it to solve its performance inefficiency. Running "select *" on a 1mm-row worldcitiespop_mil file, q takes 27 seconds compared to `zsv sql` which takes 1.7 seconds ( https://github.com/liquidaty/zsv ) and also supports multiple file joins. I'm sure q is faster once cached, but taking a 16x performance hit up-front is not for me |
