Fantastic! I was actually looking for a buggier version of postgres that won't be supported a year. That's exactly what I was looking for. > PolarDB will evolve and offer its functions and features in two major parts: Oh boy.

How do you think the next dominant Database platform will start? Is your expectation that innovation requires polish before hitting the (free open source) “marketplace”?

My expectation is that the next dominant platform will offer something unique which creates enough value that I'm willing to overlook the unfinished parts that deduct value.

When Neo4j and other graph databases went big in the past decade, they value they created: "finally! I don't have to faff around with RDBMS tables and Cobb purists to store and query my non-relational object-graph!" - despite the fact that Neo4j then (and still?) didn't support running serving databases concurrently or schema enforcement or even transactional atomicity (I think they fixed that recently?)

So in this context, what business-value does PolarDB add or create that makes it worthwhile to deal with its expected short-life?

It is alibaba: it's life might not be so short? They are huge and have a cloud provider arm.

Oh, what's going on here?

> OceanBase, the database of Alibaba's fintech company Ant Group, will be open-source soon, possibly as early as June 1, according to Sina Tech.

Also the team published many papers about PolarDB.

Sometimes I dream about a highly available multi primary postgresql.

yea, some sort of vitessdb equivalent to postgresql would be amazing!

there used to be citus but now it's part of microsoft Azure

Looking at their code tree, this is based on 11.2 (https://www.postgresql.org/docs/11/release-11-2.html): https://github.com/alibaba/PolarDB-for-PostgreSQL/blob/maste...

So this is code from two years ago missing stability fixes from upstream up to 11.12, at short sight.

True, it is developed by Microsoft and available as a service on Azure. It is also open source, actively maintained and improved, and it's a PG13-compatible Postgres extension that adds both distributed database capabilities and columnar storage. :)

It’s distributed Postgres. The same reasons you would use Cockroach or Citus instead of stock Postgres also justify using polar.

Given that there’s multiple companies that exist to scale out Postgres, someone sees business value.
