zenithm··on Graph database reinvented: Dgraph gets $11.5M to pursue unique, opinionated path
FaunaDB passed. It also has GraphQL.
zenithm··on Technical Challenges Developing a Distributed SQL Database
Shouldn't talk about Spanner and Percolator without discussing Calvin, either. https://www.infoq.com/articles/relational-nosql-fauna
zenithm··on Netlify Dev
Netlify has integration with FaunaDB for the database tier.
zenithm··on YugaByteDB – A Transactional Database with Cassandra, Redis and PostgreSQL APIs
In the NoSQL space, FaunaDB indexes are very powerful. They are term partitioned and sharded and have compound terms, covered values, transformations, etc.
zenithm··on VMware acquires Heptio, the startup founded by 2 co-founders of Kubernetes
Are they selling them for money? Or are they just things useful in the consulting process and a way to create awareness for the company?

The website advertises professional services, training, support subscriptions, and books. Redhat model I guess.

zenithm··on VMware acquires Heptio, the startup founded by 2 co-founders of Kubernetes
I'm sure everyone involved made some money but aren't they basically a consultancy?
zenithm··on Managed CockroachDB: Geo-Distributed Database as a Service
Also FaunaDB which is the NoSQL version
zenithm··on The Life of a FaunaDB Query
Good to hear from Fauna again.

I didn't know that the serialization format was JSON is that a long-term decision? Would a binary format be faster?

zenithm··on Global Multi-Cloud Replication in FaunaDB Serverless Cloud
I used DocumentDB a while ago but I haven't used the new version. It was a little strange.

You have to reason about every possible consistency configuration including transactions and indexes, but you don't actually get much control over what is indexed. And sort of like DynamoDB it doesn't really support general-purpose transactions, they have to be within a shard.

I think maybe the Mongo adapter is pretty nice though.

CosmosDB lets you set region failover priority if something goes wrong, does Fauna have a similar model?

How does an application know which region to talk to? Especially once you can select a subset of regions to be in. Some might not have the data you are looking for.

zenithm··on Graphcool – Serverless GraphQL Back End
Agree, I understand you need to have referenceable customers...but you have to actually...like...have them. I would imagine you are violating restrictions around the use of these companies trademarks.

Similarly confused by the random logos on the homepage with no context. The implication is they somehow rely on Graphcool.

zenithm··on Graphcool – Serverless GraphQL Back End
No response...I think these are companies that have GraphQL APIs, but no actual relationship with Graphcool. They shouldn't be listed as customers.
zenithm··on Graphcool – Serverless GraphQL Back End
Facebook, Github, Pinterest, etc. are listed as Graphcool enterprise customers? Is that true?
zenithm··on Spanner vs. Calvin: distributed consistency at scale
How does Volt's transaction resolution mechanism compare? It sounds like that would be a third model yet.
zenithm··on Spanner vs. Calvin: distributed consistency at scale
Welcome Dan.

What other production implementations of Calvin are out there?

zenithm··on A database built like an operating system: the architecture of FaunaDB
Detailed consistency model explanation starts on page 15.
zenithm··on A database built like an operating system: the architecture of FaunaDB
Dynamic isolation sounds cool especially without the overhead of containers. Seems obvious in hindsight I guess.
zenithm··on Show HN: FaunaDB, a strongly consistent, globally distributed cloud database
What's the biggest deployment so far?
zenithm··on Escape the cloud database trap with serverless
What are some lessons you learned at Couchbase that you are applying at Fauna?

Importance of a cloud product obviously is one!

zenithm··on 120K distributed consistent writes per second with Calvin
This is a new one to me...the referenced paper is here: http://cs.yale.edu/homes/thomson/publications/calvin-sigmod1...

How does this algorithm compare to whatever Google Spanner does?

zenithm··on RethinkDB is shutting down
Calling stored procedures microservices always makes me laugh.
