#422How's this compare to https://github.com/pingcap/tikv ? It's a relatively new distributed KV store written in Rust that also is transactional and backs the new TiDB database.
Here's a brief comparison by a tikv developer: https://github.com/pingcap/tikv/issues/2986#issuecomment-383...

I mean, PostgreSQL is MVCC and it clearly supports serializable as an isolation level... have you tried using Google? https://wiki.postgresql.org/wiki/Serializable
A lot of people apparently hated that I attacked this person, and downvoted me; but what the person who posted this comment was doing is intentionally throwing shade at and casting doubt on a project by saying "I think that the claims on this webpage don't make any sense as this should be impossible". It comes off as "oh come on, this doesn't even sound plausible; I call bullshit". This then causes people who aren't…
I suspect the downvoting was for the "LMGTFY"-esque part of your response. Dunno, don't care, just offering a possible suggestion.

#424I went to the same high school as the founders[1]. They were about the 2 best software engineers in a school with a LOT of very smart software engineers. Another pair founded Yext, which went public last year. I still consider that school the group with the highest concentration of raw brain power I've ever been a part of. I'm probably a 1% engineer, been hired by M$, FB, and Google. These guys were light years ahead…
Maybe it's just me, but the hubris in this comment seems a little excessive.
They aforementioned SWEs make themselves multimillionaires /and/ have great jobs /and/ get praised by their peers, yet now everyone else has to bow down to them... over claims they were great programmers in high school? Is an appeal to your own experience the best way to make yourself seem relevant here?
It's an incredible DB system, but it ain't the Second Coming. Calm down.

Dont you need a M.S. degree to call yourself engineer?

Does CockroachDB use TrueTime or a similar technique?
See CockroachDB’s Living Without Atomic Clocks [0]. TrueTime [1] is a proprietary Google technology.

Do they do something like: http://fireless.cs.cornell.edu/publications/dtp_sigcomm16.pd... ?

I absolutely was not throwing shade at the project, I was just trying to understand. I have a great interest in distributed systems that can efficiently implement serializable ACID transactions, and looked at their documentation with great interest to see how they implemented it. I honestly thought that MVCC could only efficiently implement Snapshot Isolation. So I figured my understanding was wrong, or at worst there's a typo in their documentation and they use something other than MVCC under the hood. Either way, I wanted to know more about their architecture.
I'll take your feedback under consideration, and I'm sorry to have irritated you.

> That API is gnarly. Out of the many MongoDB criticisms, this one is valid. This https://www.linkedin.com/pulse/mongodb-frankenstein-monster-... article is quite right about it (note: endorsing the article does not mean I endorse its author by far). Other than that, they totally did a fake it until you make it with MongoDB 3.4 passing Jepsen a year ago and MongoDB BI 2.0 containing their own SQL engine instead of wr…
What specifically are you trying to avoid endorsing about the author of the LinkedIn post to which you linked? I couldn't find anything from a cursory web search.
You could try adding controversy to the author name and searching then. As mst correctly notes, I am trying to avoid reigniting said controversy while indicating my distaste.

I'm not familiar with FDB but what you say sounds almost too good to be true. Can I use it to implement the Google Datastore api? I'm trying for years to find a suitable backend so that I can leave the Google land. Everything I tried either required a schema or lacked transactions or key namespaces.
Hey there--I'm an engineer on the Cloud Datastore team. I'd love to know more about what your needs are if you're willing to share.
I've forked the official SDK so that I can get extra functionality but it's quite hard to keep it updated when internal stuff changes. There is no way I can contribute.
I can't use it everywhere I want...shortly said it's not open source and this sucks.
Re: Apple open-sources FoundationDB
#430This is INCREDIBLE news! FoundationDB is the greatest piece of software I’ve ever worked on or used, and an amazing primitive for anybody who’s building distributed systems. The short version is that FDB is a massively scalable and fast transactional distributed database with some of the best testing and fault-tolerance on earth[1]. It’s in widespread production use at Apple and several other major companies. But the…
How scalable and feasible to implement a SQL Layer on top of SQLite's Virtual Table Mechanism (https://www.sqlite.org/vtab.html) which redirects the read/write of the record data from/to foundationdb?
