After about three weeks I hand drove three agents in parallel for 8-10 hours/day. There is very little automation.

For DoltLite in particular, push/pull/clone/fetch are an elegant solution to the local-first sync problem. You can use data conflicts instead of CRDTs.

In general, branch and merge seem to be required primitives for agentic writes. Would you let a coding agent change your code if it wasn't in Git? We think the same will apply to databases.

I'm the CEO of a company that's focused on version control for structured data ie. SQL tables and JSON documents. We share the "version control for everything" vision and think an agentic world needs it.

I’m the author of the linked Prolly Tree article and I launched a prolly tree visualizer last week.

Thanks for being an early adopter. We learned a lot trying to support your use case and you’re still customers so it can’t have been too bad…

We actually wrote another blog about this because I had the same question. I am the CEO of DoltHub so I can have my engineers write stuff to explain it to me :-)

We built a MySQL-compatible one and are building a Postgres-compatible one :-) Free and open source.

We use the reset functionality to speed up our tests.

Coming soon we'll have the ability to replicate a branch HEAD to MySQL as well.

Version Control is not the type of thing "mainstream DBs would adopt".
We needed to build a custom storage engine to make querying and diffing work at scale:
https://docs.dolthub.com/architecture/storage-engine
It based on the work of Noms including the data structure they invented, Prolly Trees.

Most direct users of go-mysql-server use it to test Golang <> MySQL interactions without needing a running server.
We here at DoltHub use it to provide SQL to Dolt.

> Why is Dolt MySQL flavored?
TLDR; Because go-mysql-server existed.

We have a Postgres version of Dolt in the works called Doltgres.

We might have a go-postgres-server package factored out eventually.

You can do this with a setting:
