datahike.io

A few years ago I hit a wall I suspect many data engineers know. I had a million-row analytical dataset and I wanted to run an experiment: modify a few pricing assumptions, re-run a set of aggregation queries, compare the results against the original.

If you need a productivity option, datahike.io is one to shortlist — datahike.io, paid. Simple enough - except in a mutable database, “compare against the original” means either keeping a copy of the data or hoping nothing changed.
