Why does clean room even matter given SQLite is in the public domain?

Still, I think it’s the right default to start with serializable. Then when you have performance issues you can think long and hard about whether relaxed isolation levels will work in a big free way. Better to start with a correct applicati

About time for the 6th Edition, eh? What would folks include in it? - Vector databases and hybrid search? - Object storage for all the things? Lake houses. Parquet and beyond. - Continuously materialized views? I'm not sure this one ha

This is nice double entendre because tonic is a pleasant gRPC server library in rust! https://github.com/hyperium/tonic

It should be this way. Clients should have some protocol to communicate the schema they expect to the database probably with some versioning scheme. The database should be able to serve multiple mutually compatible views over the schema (st

You’re right that it would run on a block chain, but that fact would primarily exist to power some marketing. Everybody would end up interacting with it through a single centralized web site and API because it’s the only usable way to get i

Thank you for writing this. This comes up constantly, and it'll be great to have another reference to cite. Another interesting thing about TPC-C is how the cross-warehouse contention was designed. About 10% of new order transactions n

Folks, for the love of god, please please stop running TPC-C without the “keying time” and calling it “the industry-standard TPCC benchmark”. I understand there are practical reasons why you might want to just choose a concurrency and let i

Some time ago I worked on cockroachdb and I was working on implementing planning for complex online schema changes. We really wanted a model that could convincingly handle and reasonably schedule arbitrary combinations of schema change stat

While that’s sort of true, there’s a lot of language specific things that go into making the UX of a debugger pleasant (think container abstractions, coroutines, vtables and interfaces). Specifically async rust and Tokio gets pretty interes

How would you compare that to, say, go? I think the unit of distribution in go is a module, and the unit of compilation is a package. That being said, by using `internal` packages and interfaces you can similarly create the same sort of opa

My biggest issue with rust after two years is just as you highlight: the mod/crate divide is bad! I want it to be easier to have more crates. The overhead of converting a module tree into a new crate is high. Modules get to have hierar

Literally all three of their required features which were not “standard” for swiss tables were requirements for the go implementation. See https://go.dev/blog/swisstable for a nice post on that project.

I’ll nitpick you back: if done correctly, consensus can have quite positive scaling consensus groups can have quite a positive impact on tail latency. As the membership size gets bigger, the expectation on the tail latency of the committing

Cockroach really doesn’t have limitations when it comes to queries. It is kinda magic in that regard. The single partition queries are the special case and are treated as rare. Cockroach ranges are quite small compared to other systems (~25

I made an implementation in clojurescript that animates the algorithm as it goes a while back: https://voronoi.ajwerner.net/#/app-diagrams It’s a very beautiful algorithm. However, after that project I sort of came to

I don’t think in NYC it’s fair to argue that there’s relatively little interest in making transit something people want to use. We can debate about whether the efforts are effective, and certainly many aren’t. However there are vast sums in

This feels like a crazy take. The stronger labor laws part I hear, but the anti-urbanism part I don’t. Do you have data or an ideology or something? Seems like you’ve been radicalized to a point of view, but by what?
27.
by vvern 2y ago
Have you taken a peek at sqlsync? It's a cool take where you write your entire application logic to operate as transactions and queries over a sqlite database but you do it in wasm so that the same transaction logic can run everywhere.

If that’s what you want, try cockroachdb serverless. Scales from zero in well under 1s even for multiregion. Also actually has quite good Postgres support these days.

One approach to mitigate the connection problems for tpcc would be to utilize a connection pooler like pgbouncer or yandex/odyssey. It’s certainly more complexity. Another suite to look at is sysbench. It’s very flexible, for better or

Can people please, for the love of god, stop running tpcc with think time disabled. When run in this way it is not the TPC-C benchmark, and is not "simulating real database workloads that is considered a modern standard in database app
