"Of course there's going to be less questions" Yet there are counter examples that show that can't be the complete story: http://sotagtrends.com/?tags=[jquery,python]&relative=false

It doesn't, the authors are calling this out to limit the scope of linearizability to per-object. You're thinking about strict serializability. The authors mention that transactions can be implemented in a way to support this by i

Our network definitely makes a big difference, but even we don't just use straight up vanilla Paxos.

Need some non holiday time to read this fully, but it's worth noting that aside from Spanner, Cloud Datastore (using Megastore tech) and Cloud Firestore (using the same tech as Cloud Spanner) all do Paxos across several data centers o

Yet many non-relational systems do support ACID transactions across multiple resources. Just from Google there is Megastore, Cloud Datastore, Spanner, Cloud Firestore

Nice! Will you be adding something like a categories tag? Any initial feedback on using Cloud Firestore you'd want to share? [Good | Bad]

It does not use CRDTs as they cannot be used to handle all the update requirements of this system. It uses Paxos as the consensus algorithm, along with internal systems like the TrueTime API to enable us synchronously replicate across multi

Hard to explain externally, but it relates to RAM size allocation + throughput in the underlying distributed database system.

Thanks for the feedback, this request is definitely been a frequent one. :)

We've also tried to be transparent and document our current limits here: https://firebase.google.com/docs/firestore/quotas

Nothing we can share at this time. Really looking forward to the feedback we get now we're in beta as this will feed into our GA plans.

Sure, it's strongly consistent on the server-side part (strict serializability), whereas for the mobile/web clients we make sure we move you through consistency snapshots with the real-time sync functionality.

Great question! I'm the PM for both Cloud Datastore and Cloud Firestore. The biggest difference is the integration with Firebase, so you have access to Mobile (iOS/Android) and Web SDKs along with a native offline mode. This comes

Except, given that both models ended up #1, and #2 respectively, doesn't it imply that both models can work and other factors are more important in success? Following that, doesn't it imply that shareholders should/will care

It is refreshing to see an article from a distributed database vendor that gives a reasonably good description of the trade-offs they make and why - without the all the nonsense hyperbole claiming they're the best for everything withou

One thing I like about Lovefield is the ease of choosing a storage layer: lf.schema.DataStoreType.FIREBASE You can use it with in-memory (no persistence, .MEMORY), IndexDB (local persistence, .INDEX_DB), or Firebase Realtime Database (cloud

The counter arguments include Google, Apple, Microsoft, etc. I think the big vs small comparison is flawed. I've seen some atrocious code produced by small/medium sized outfits. My fondest memory including auditing code from a 3 p

I thank you for the compliment, but I am a lowly PM rather than an engineer, that doesn't find Cloud Databases [1] any more esoteric than the Cloud in general. :) You'll probably find there are a lot of distributed database geeks

To add extra color, for about $3M/month @ list prices of Cloud Datastore [1], you can, in a Multi-Region active-active synchronous replication configuration, run a workload with the following profile: Reads: >1.1M entities/seco

Take a look at Cloud Datastore's pricing, which is probably a leader in this area (I work on it).

We have a series of locations that determine replication topology, but you cannot do à la carte region selection at this time. Under the hood we run on at least 3 independent private super fast network fabrics between regions, so we have a

Thanks for the feedback! I happy to hear you gave it a shot and I've heard several times about it being used successfully from Lambda (hopefully people can look at GCP's Cloud Functions now, but I'm biased). Sorry to hear it
