Re: Citus Unforks from PostgreSQL, Goes Open Source
#2If anyone from Citus is reading this: how does this affect your business model? I remember when I asked at Strata conf a couple of years ago why isn't your stuff Open Source, the answer then was "because revenue". So what changed since then?

#3This is fantastic news! Postgres does not have a terribly strong High Availability story so far and of course it also does not scale out vertically.
I have looked at CitusDB in the past, but was always put off by its closed-source nature. Opening it up seems like a great move for them and for all Postgres users. I can imagine that a very active open-source community will develop around it.

#4This is awesome! Tebrikler (congrats) on the release of 5.0 and going OS, definitely great news.
Can you publish competitive positioning of Citus vs Actian Matrix (nee ParAccel) and Vertica? I'd love to compare them side by side - even if it's just from your point of view :-)

#5My guess is that Citus is making enough money from consulting that they don't need to keep this code closed source when they can profit from free community-driven growth while they are expanding their sales pipeline through consulting.

They offer an enterprise paid version with more functionality.
"for customers with large production deployments, we also offer an enterprise edition that comes with additional functionality"

We've been running CitusDB for a couple years now at CloudFlare for serving aggregated analytics to customers (cf. https://blog.cloudflare.com/scaling-out-postgresql-for-cloud...).
It's a good product, and it was even fairly easy to do a major version upgrade / cluster relocation. At least as easy as such a thing can be. :-)

#10This is awesome. I have experience with running a CitusDB cluster and it pretty much solved a lot of the scaling problems I was having at the time. For it to go open source now, is of huge benefit to the future projects I have.

This is fantastic, sounds like the setup process is much simpler.
I wonder if they have introduced the Active/Active Master solution they were working on? I know before, there is 1 Master and multiple Worker nodes. The solution before was to have a passive backup of the Master.
If say, they released the Active/Active Master later on this year. That's huge. I can pretty much think of my DB solution as done at this point.
