Agents Need Tests Example Agents need tests. Dolt is the only SQL database with a built-in test engine. Dolt is the database for agents. This article will explain this concept with an illustrative example.

This blog illustrates how Dolt and Dolt CI can enhance an agentic workflow.

Agents Need Tests Agents need tests. Dolt is the only SQL database with a built in test engine. Dolt is the database for agents. This article will explain this concept.

Dolt is perfect for the agentic wave that is coming. Agents need branches. Agents also need tests. Dolt is the only database with both. Agents can run Dolt CI tests as they make changes on clones or branches of your database.

Protecting against Rogue Agents If you give your agents too much freedom, they might go rogue. Here's how to protect your data against them.

Protecting against Rogue Agents If you give your agents too much freedom, they might go rogue. Here's how to protect your data against them.

Dolt is the perfect database for agentic workflows. You can implement workflows that work safely on branches, and their work can be verified before merging. If the agents go rogue, just revert their changes to a previous commit. This is perfect for Replit users and similar tools.

#ai #replit

These tools need a database that you can branch, merge, and have human review the changes to avoid this. Dolt can do all of those things and we are free/open-source.

Previewing Dolt 2.0 Two years ago in May, we announced Dolt 1.0. We're working on Dolt 2.0. This article previews what will be in Dolt 2.0 and tells you how you can help us get to Dolt 2.0 quicker.

Dolt 2.0 is coming in early Q4. What's in store?

*Automated Garbage Collection on by Default
*Archive Compression on by Default
*Performance Parity with MySQL on sysbench
*Beta Vector Support

This blog gives a preview.

An Agentic Helpdesk Agentic workflows need branches. Here is a sample app showing why.

Agentic workflows benefit from the ability to branch and merge data, which only Dolt can do. To prove our point, we built a sample app that demonstrates agentic workflows built on top of an open-source helpdesk system, backed by Dolt.

Conjoin Means Bugs Conjoin is an internal detail about Dolt that many know nothing about. Let's change that!

A great benefit of being open source is that we don't really have any secrets, and so we can share every little detail of how Dolt works through our blog and docs. The "Conjoin" process is one such detail which we've never talked about before until now.

Doltgres Correctness Testing Check out the progress Doltgres is making toward Postgres compatibility! It’s not great yet, but it’s slow and steady.

To ensure Doltgres behaves like Postgres, we've started running it through Postgres Regression Test suite. This process performs correctness testing for Postgres-specific features.
