This article doesn’t present much motivation for why you would do this.
To me it reads a bit like, how we built our office without desks: it turns out if you stack two chairs on top of each other, you can balance your laptop on the top and you’ll also have a shelf on the bottom for your things.

For those working with databases, it's easy to come up with a bunch of reasons. ORM is a necessary evil when working with RDBMS, as are things like schema migrations that can easily result in loss of data (I.e., dropping columns or tables).
What if all we need is dumping a big old JSON in a container?
This idea is very enticing. The scale of this whole NoSQL thing is pretty telling.
The blog presents a thought provoking question: what if we don't actually need a full-blown database, and instead we only care about things like unique constraints, transactions, indices, and history tables.
Articles like this remind me of that Innovation Tokens article.
Your time and attention is precious as a developer. I'm absolutely sure it's possible to implement uniqueness constraints, transactions, indices, and history yourself, but is that really the most valuable use of your time? There's probably not a need for you to have a unique solution, so you're quite literally just re-inventing something someone already had for not a lot of benefit.
Wouldn't your time be better spent actually solving the problems that whatever you're building is supposed to solve?
There is a simple version of this idea that really resonates with me.
For about a decade, I've been using flat files on disk or object storage for most of my side projects. There's even a python library that handles some of the plumbing for you [1].
If you don't have strong record-level concurrency needs then it's a lot nicer, easier, cheaper than a relational or document database. And if you do need that, you can design your data model around what defines a record.
This is frustrating to read. Tigres is built on FoundationDB, but doesn't expose all FoundationDB operations like transactions, range reads, and get mapped range. They go through all sorts of complications to handle these issues, including a database for caching (and they don't consider thundering herd problems).
Also, the database is the last thing you want to re-invent unless your business is explicitly building a db (even then it's best to re-use a db like all the postgresql forks that have existed)
Absolutely no mention of Iceberg or Delta Lake, which have had many of the same properties for years. I wonder if they are aware of them, or otherwise why they invented something new.
I generally don't read low-quality AI slop though, so its possible I missed an explanation that didn't contain those key words.
Author here. Ampbase is an OpAMP control plane for agent fleets, and this is how it runs without a database: conditional writes for uniqueness and compare-and-swap, one bucket per customer so isolation isn't a WHERE clause somebody has to remember, ULID keys so history is a prefix list.
Two things the post doesn't cover and I'm happy to get into. What closing the cross-region lost update actually took: annotating the RPCs that depend on a compare-and-swap and replaying those to a single region, with a client-side guard. And the read amplification, which we have a plan for but waiting on a clear signal for when it’s needed.

People who grew up with assembly language or locking primitives are fairly likely to use compare-and-swap because it's literally the commonly understood term for it.
> In practice, when you reach for a database engine you're actually reaching for four basic features: unique constraints, transactions, indices, and history tables. In order to use Tigris' global object storage as a database, we had to implement all of these primitives ourselves.
Not sure why the "without a database" is or isn't so important, why is it mentioned so often and why the article flip-flopping between "we don't have a DB" and "we're effectively building our own DB"?

What if we only need a subset of those?

What if you just ran FoundationDB instead?
Would that let you do collaboration blog-posts with another VC-funded startup though?
Also, the database is the last thing you want to re-invent unless your business is explicitly building a db (even then it's best to re-use a db like all the postgresql forks that have existed)
good news, FoundationDB is already invented, and just slightly more tested than others on the market.
If you only have binary encoded protos to worry about (which is typical) then you can rename fields.
Did it take 10 seconds of prompting? Or hours of thought, trial error and revision? Especially when asking people to read for 20+ minutes...

This is Claude between the lines admitting none of it was needed. Postgres on a VM would be doing just fine right now.
edit. Clearly the joke about "lo-and-behold" didn't land well with the bots...
