I love this comment, but presumably there's a need for databases that are well suited for write heavy workloads. Also there's no great story for starting out with an RDBMS and then scaling out. Right now if you're with MySQL you have some options to scale out with read replicas, and then eventually replicate to a TiDB cluster. PostgreSQL I guess there's cockroachdb, but it's kind of meh.

I believe Cloudflare usage of PostgreSQL is "write heavy" and is a RDBMS that scaled out very well for them.

They are using CitusDB but it's still RDBMS and support most PostgreSQL SQL query without the need to rewrite your query or change your schema.

They moved to Clickhouse recently, though: https://blog.cloudflare.com/http-analytics-for-6m-requests-p...

In fact Youtube for a long time was running on MySQL with a tiny service called "vitess" on top of it to handle (Sharding/partitioning) automatically.

I dont know if they are still using Vitess or migrated to Google other relational Database "Spanner"

YouTube switched some Vitess workloads over to Procella. http://www.vldb.org/pvldb/vol12/p2022-chattopadhyay.pdf

In general I've noticed that people outside Google assume that Spanner is much more popular than it really is.

To be honest I am surprised its not more popular.

if you work at google and its one of the option to choose from! Is there any reason to "not" choose spanner for new project and instead use something else?

That's true, I forgot about Citus.
