A) Postgres easily scales to billions of rows without breaking a sweat. After that shard. It’s definitely negotiable.

So does a text file.

Statements like yours are meaningless when you aren't specific about the operations, schema, access patterns etc.

If you have a single server, relational use case then PostgreSQL is great. But like all technology it's not great at everything.

[scosman]

The use a text file.

In all seriousness, calling Postgres’ scalability “not-negotiable for most use cases” is wild.

[threeseed]

What's wild is you misrepresenting what I said which was:

"built-in, supported, proven scalability and high availability"

PostgreSQL does not have any of this. It's only good for a single server instance which isn't really enough in a cloud world where instances are largely ephemeral.

[tristan957]

Do you mean ephemeral clients or Postgres servers?

If multiple nodes are needed, then why MongoDB and not a Postgres compatible distributed product like CockroachDB or YugabyteDB?
