Misleading title -- it isn't claiming that there are any newsletters generating $22M a year individually. It's just saying that the top 27 (why 27?) newsletters in aggregate make at least that much.

Yes, exactly!

Storage is replicated across a handful of nearby sites. It does add some latency to writes, but that's preferable to Objects being offline or lost in the case of hardware or network failures. There's no Jepsen testing in the works

It means that you'd use a different ID to access each document. Each document's Durable Object would run the same code as part of the same namespace of Durable Objects, but have their own in-memory and durable state. Check out the

With how often I've seen spaced repetition mentioned online recently, I'm starting to assume there's a grand conspiracy that's trying to use spaced repetition to trick me into remembering about spaced repetition.

In this case it actually makes sense because it's not easy to find a non-paywalled version of the paper.

To add on to that last point, you don't need to pick in advance which region or regions your code will run in. You push your code once, and it will run in whichever edge locations receive requests, potentially all 165+ locations if you

Yeah, it appeared to just be general resource contention from having to share the machine -- CPU interrupts, less memory available, etc. I'll note, though, that the 5% number is when using host networking for both Cockroach and the cli

WAN-optimized consensus protocols like Mencius and Egalitarian Paxos indeed are better for writes because any node can commit a write in one round trip, but they don't allow for reads with zero round trips. Every read must go through t

It's actually even in 1.0.0! We just haven't written about it previously. The doc you found is the best resource. If you want even more detail, you can check out the original RFC: https://github.com/cockroachdb&#x2

It helps with both, but is more dramatic for reads. Reads go from 1 RTT to 0 RTTs, while writes go from 2 RTTs to 1 RTT. For example, consider a cluster in which the nodes are 200ms RTT away from each other. * A read will take 200ms if the

For single-key operations only, but that is still much better than the average system he's looked at.

The Dynamo paper is from 2007... How much has Amazon published about their internal workings since then?

CockroachDB reads are strongly consistent, not eventually consistent. You don't have to wait at all.

Yes, it works. Your latency will just be correspondingly higher (due to the speed of light). We are constantly testing a cross-region (i.e. US-East and US-West) cluster and have periodically run tests on cross-continent clusters (US to Asia

It's not clearly advertised on their landing page, but it looks like the lifetime registration fee is being waived for a limited time, so if you're interested at all you should consider signing up now.
