MongoDB database migration

When you’re developing a fairly large application, and you design things properly, you will almost inevitably end up distilling out some nice things into independent, well-factored libraries – because, Separation of Concerns, you know… 🤓

That also happened this Friday, when Fleet Manager got its evolutionary database design library for MongoDB moved out into its own project: Mongrow.

With Mongrow, you can write database migrations as C# classes and have them executed in a safe, consistent, and deterministic manner, probably when your application starts up.

Its design is very much inspired by migr8, another little database migration library, only made for MSSQL and Postgres.

So… if you’re using MongoDB in .NET, you might want to check it out: The binaries are on


MongolianBarbecue is out as 1.0.0

It’s a nifty little tool with a silly label, but since it implements queues on top of MongoDB, the name was inevitable! 🤠

So, if all you have in the world is MongoDB, and you want to do some messaging, you can do this:

var config = new Config("mongodb://MONGOBONGO01/some-db", "messages");

to create a configuration, and then you

var producer = config.CreateProducer();
var message = new Message(Encoding.UTF8.GetBytes("hei"));

await producer.SendAsync("destination-queue", message);

to send a UTF8-encoded text to a queue named destination-queue, and then you

var consumer = config.CreateConsumer("destination-queue");

var message = await consumer.GetNextAsync();

// ... handle message here

to receive the message and handle it.

You can read more about it on the GitHub page, and you can get the binaries from your favorite package repository.
