Thanks for the shoutout. At some point if you find yourself with some spare time you can check out our new FQL version. It's closer to JS in terms of syntax now, but still a small,…

One might say uncomfortably slow.

The NoSQL movement overstated how important the A in CAP was. Relatively few systems need _all_ nodes to be available, compared to those that benefit from strong consistency, espec…

I'm clearly biased, but at least in my experience, while this is technically true, you're still dealing with XML (and now JSON) shoehorned into a tuple-based context. In other word…

If your current stack is working for you, that's great. The main advantages of Fauna vs say MySQL are going to be: - Fauna is distributed and multi-region and therefore more resili…

Getting the best of both worlds is what we're trying to achieve with Fauna, at least for OLTP use-cases. I'd be curious to hear what challenges with you ran into with other NoSQL d…

While, making it easy (and possible in the first place) to write procedural code directly in a transaction is a core part of FQL's design, it is certainly possible to implement saf…

They don’t bother and just use search: https://futurism.com/the-byte/gen-z-kids-file-systems

There’s no catch. No database is going to work for every use case, but we’ve built FaunaDB to be general purpose, and suitable for many of them.

Fauna, Inc. | Remote | Full-Time Opportunities | https://fauna.com/company At Fauna, we’re building the serverless database for modern apps built on JAMstack. If you want to work o…

Calvin has been an elegant protocol to work with in practice, and has pretty radically simplified FaunaDB's implementation of transactions compared to classic 2PC. Writes are commi…

Yes, I was not trying to imply the bugs Jepsen found haven’t been fixed. However the possibility of causal reverse is a characteristic of CRDB’s architecture, so you can still obse…

Isn’t that just describing reintroducing waiting out the uncertainty window in order gain back external consistency? I’m not sure that ends up being substantially different from Tr…

I don’t know of an article describing it offhand. The issue arises where each transaction occurs on a different node or set of nodes, and the causal link between them is external t…

Cockroach Labs themselves freely admit CRDB allows for causal reverse anomalies [1], and Kyle reproduced it in his Jepsen analysis [2]. HLCs don't prevent causal reverse, because t…

As others have commented, most widely deployed DBMSs provide deadlock-free serializability. FaunaDB is a commercially available implementation of Calvin that makes deadlock free se…

This advice is highly implementation specific and unnecessarily dangerous. For read only transactions, a well designed system will be able to provide SNAPSHOT isolation with little…

Serializable Snapshot an implementation strategy for providing Serializable isolation. In PostgreSQL if you ask for Serializable you get SSI.

Sorry I can't let this go unchallenged. Again, you are inventing an architectural deficiency where the is none. The log in Calvin is partitioned and does not require all transactio…

This take on Calvin is inaccurate: Under contention, a Calvin-based system will behave similarly to others which use optimistic locking schemes for Serializable isolation such as P…
