The cost to run those benchmarks with AWS was close to $50,000 just in infrastructure cost ( that was the main reason we jumped from 16 shards to 64 shards at the larger instance size, we wanted to show the top end, but we didn't have

Its not, its still read committed. Its the same thing as if you had to read from two rows in a transaction, and your isolation was read committed, and both those rows would be modified by a different transaction. Its possible you read the f

The data will be committed, but you may get a subsequent read that has the previous value, before it is overwritten by the final value. This would only occur if the shard where the commit is occurring fails, while the promoted shard replays

Yes they are normally isolated, however its only at a READ_COMMITTED level, and a nuance of the implementation is that you may see committed data rolled back by the protocol in the event of a failure. Its still technically READ_COMMITTED, b

We will normally list it as ACI*D since there is a situation where you can break isolation.

That is correct, this was done in partnership with AWS to show off Aurora, however we have achieved similar results with stock MySQL. We are pretty confident that with standard MySQL using MyRocks and some high end storage devices we will b

I am one of the Maintainers of Vitess and I just wanted to pipe in on a few points. The comparison chart lists vitess as not having "High Performance" due to what they are saying is a single coordinator node ( vtgate ). You can ac

You are totally ignoring the main point of the articles you linked! The reason we don't do it in america isn't because we have a lower risk tolerance, its because we built infrastructure that doesn't allow it[1],[2]. You link

Its pretty common to have to deal with Ad hominem attacks when your pushing for change so all I can hope for is you can see how much your resistance to change is hurting those around you.

But what you don't see in that 0.01% statistic is we have already acclimated to a world where kids are fortified against being hit by cars ( and it still happens ). The days of walking to school, the local playground, or a corner store

It doesn't and the fact you latched onto that statement makes me thing you don't actually understand it. You want to believe this is just over protective parenting, but you don't understand how the sprawl of modern developmen

Getting hit by a car is the leading cause of death of children[1]. Its not helicopter parenting its knowing that more kids die from cars then by any preventable cause. Anyone with kids knows the danger having kids on or near busy roads, and

In so much as you can't get close to zero without radically changing how we build and live in this country you are correct, but the question is why wouldn't you want to make the changes to target zero deaths ? Not only would you b

Of all the things I am concerned about for my 3 school aged children its them getting hit by a car. It makes it so I am afraid to let them go anywhere without me or another adult. It represses freedom in a way no other technology has. The o

I am only aware of one study that found it was actually 97% of full time engineers couldn't write code[1], but I don't think that was a very rigorous study. The best evidence would be the very well known blog post by Jeff Atwood [

I agree that you can't typecast everyone who has worked in a specific platform. There are lots of high quality developers out there working on all sorts of things, and as an industry we put too much emphasis on resume's which can&

Its not about learning the language. Take a Java developer who is used to Eclipse and tell them from now on they need to write Maven files directly and learn how to build and test from the CLI because thats how your CI works. Same thing wit

For the specific example given I have turned down many individuals who sound like they have a similar background because they could not figure out how to work outside of their toolchain. I see it all the time with .NET and Java developers,

This really makes it seem like you have never used a database system at scale. There are reasons why systems like MySQL let you turn them off, and they are some of the same reasons why pretty much everyone who uses a database at scale has s

Every time I have seen a database use foreign keys there has been data corruption, because everyone thought foreign keys were declarative and not procedural. Just because you have a foreign key doesn't mean it was always there or that
