"Basic" (i.e. full) backups have been included in the OSS version since its November 2020 release (20.2): https://www.cockroachlabs.com/blog/backup-restore/ They are still pretty l…

> My current database is in a private subnet, it would be unfortunate to have to open it up to the world to take advantage of this. Agreed, this is a big current limitation. As men…

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 a…

Yes, exactly!

WebSockets are actually already supported! See the "Can Durable Objects serve WebSockets?" section from the closed beta announcement last fall: https://blog.cloudflare.com/introduc…

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 networ…

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 th…

I'm not a tax lawyer, but 20% is the long-term capital gains rate for earnings greater than $400k or so - https://www.nerdwallet.com/blog/taxes/capital-gains-tax-rate... That page …

They switched to calendar-based versioning earlier this year with the 19.1 release, for reasons explained in this blog post: https://www.cockroachlabs.com/blog/calendar-versioning/…

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 reme…

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 …

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 wh…

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 re…

Yes: https://github.com/cockroachdb/cockroach The parent poster was referring to CockroachDB as CRDB.

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: …

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 200m…

Why didn't they just set up a Patreon page for themselves?

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 pe…
