Maybe you should start; it would be a good A/B test.

Netlify Dev also includes support for accessing FaunaDB GraphQL Cloud, launched in beta today ( https://fauna.com/blog/getting-started-with-graphql-part-1-i... ). We are working on adding support for a 100% local develop

The example here: https://apple.github.io/foundationdb/developer-guide.html?hi... suggests that serializability is violated when atomic ops are mixed with regular ops on the same key. Note that transaction pipelining i

Just because Percolator was implemented to provide transactional isolation in an OLAP system doesn’t mean that the algorithm doesn’t apply to OLTP contexts. FoundationDB and Percolator were developed independently, but the fundamental princ

It seems like it should be able to offer strict, but the official docs suggest otherwise and clearly distinguish it as different than serializable: “FoundationDB provides the strongest possible consistency model, sequential consistency (clo

At Twitter in the early days it was janky/jankiest. “Jankest” is also new to me. The opposite of janky was prostyle. There was no middle ground.

This is a very good question, and to a substantial degree, this is what we did. We have internal QA systems that overlap Jepsen that catch most issues. We also ran our own Jepsen tests on the core product properties last year, fixed some is

If only this were the case! Unfortunately it is not practical to reliably maintain single-digit millisecond clock tolerances in the public cloud as an end user via NTP. The entire software/hardware/network stack has to be tightly

FaunaDB can tolerate the loss or partition of a minority of replicas (datacenters, AZs, or racks) in a cluster, so if you want to tolerate more concurrent failures, just add more replicas. For example, a 7 replica FaunaDB cluster can lose 3

Yes, for sure. They are both distributed object stores and share inspiration from the Linda/tuplespace lineage, as well as relational and document databases in FaunaDB's case. FaunaDB supports function execution in the database, i

Hmm, when did you try it? FaunaDB and the cloud service have changed a lot in the last few years, and performance is always improving. Typical write latencies in Cloud are in the 100ms range because the data is globally replicated. Typical

Well, it is a general-purpose database with a document-relational programming model. It's a good choice when correctness, high availability, and flexible data modeling matter, like the core business objects of a service or app. Current

So excited to see this; this is the culmination of three months of very hard work by both teams. FaunaDB 2.5 passed the core linearizability tests for multi-partition transactions immediately. To my knowledge no other distributed system has

Amazing and poignant story; thank you for sharing. I do wonder if there was a path for Gumroad to become a Shopify killer, instead of focusing on sellers too small and unsophisticated for Shopify, which limited the addressable market.

This is correct, but then what happens when the UV partner closes up too? The whole point of UV was to de-risk committing to a specific streaming service because your purchases were portable, like being able to put a DVD you own in a differ
