I want to add my sympathies for those looking at migration in the near future. At least there are tons of good projects out there these days!
If it is helpful to anyone our company provides a data platform designed for high speed analytics at scale. It's certainly not a 1:1 alternative, but if you are looking for an all-in-one solution with a lot fewer moving parts we might be the right answer. We're happy to provide an extended free trial through September 30 for anyone looking at migration alternatives:

In any case we wish everyone an easy transition to your next solution!
