PolarDB, yet another open source database system based on PostgreSQL

Oh, what&#x27;s going on here?<p>&gt; OceanBase, the database of Alibaba&#x27;s fintech company Ant Group, will be open-source soon, possibly as early as June 1, according to Sina Tech.<p><a href="https:&#x2F;&#x2F;cntechpost.com&#x2F;2021&#x2F;05&#x2F;27&#x2F;ant-groups-in-house-database-oceanbase-said-to-be-open-source-soon&#x2F;" rel="nofollow">https:&#x2F;&#x2F;cntechpost.com&#x2F;2021&#x2F;05&#x2F;27&#x2F;ant-groups-in-house-databa...</a><p>Also the team published many papers about PolarDB.<p><a href="https:&#x2F;&#x2F;scholar.google.com&#x2F;scholar?hl=en&amp;as_sdt=0%2C48&amp;q=%22polardb%22&amp;btnG=" rel="nofollow">https:&#x2F;&#x2F;scholar.google.com&#x2F;scholar?hl=en&amp;as_sdt=0%2C48&amp;q=%22...</a>

Looking at their code tree, this is based on 11.2 (<a href="https:&#x2F;&#x2F;www.postgresql.org&#x2F;docs&#x2F;11&#x2F;release-11-2.html" rel="nofollow">https:&#x2F;&#x2F;www.postgresql.org&#x2F;docs&#x2F;11&#x2F;release-11-2.html</a>): <a href="https:&#x2F;&#x2F;github.com&#x2F;alibaba&#x2F;PolarDB-for-PostgreSQL&#x2F;blob&#x2F;master&#x2F;configure.in#L20" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;alibaba&#x2F;PolarDB-for-PostgreSQL&#x2F;blob&#x2F;maste...</a><p>So this is code from two years ago missing stability fixes from upstream up to 11.12, at short sight.

What are people&#x2F;companies using currently to make their postgres database distributed these days?<p>Currently running my app + db on Heroku in the EU and would like to scale out since latency is abysmal for users in Australia and Asia.

It seems that Alibaba is going more open source than Amazon for their clouds services. That’s interesting and they may use this approach as a key differentiator.

No commit history? It would have been interesting to follow the development work to see what changes they&#x27;ve made compared to PostgreSQL.

What more db’s are based on Postgres?

This field is getting crowded wonder if there will be some type of consolidation.

I&#x27;d love to try this out. What I&#x27;m missing though is at least some Docker based deployment not involving building stuff from sources and reinventing distributed architecture myself.

Can anybody comment on whether this actually works properly and does what it claims to do?

What are the differences between this and YugobyteDB?

“high availability through Paxos based replication”. I thought Paxos is supposed to be a CP system.

Why wouldn’t I use cockroachDB?
