Every statement that passed quotation and attribution checks. Mix any filter with any other: certainty 1/5, debate potential 5/5, or both at once.
why aren't all 16 resolved? a statement only gets an assessment when the public record can support or contradict it. opinions and what-ifs never can, and 0 checkable ones are still open, waiting for their date. predictions held up or didn't; assertions are supported or contradicted. on every card: ▮▮▮▮▮ certainty · ▮▮▮▮▮ debate potential. speakers are clickable
Stewart: Cockroach Labs adopted BSL, open-sourcing code after three years
“One of the big things we did is we did change our open source license. So it's still source available. It's still free, but we moved from Apache to a license called the business source license. Which is just like Apache, you can use the software, you can redis…”
Stewart: CockroachDB beats Amazon Aurora heads-up in single data centers
“We're still winning heads up versus Amazon Aurora in single data centers.”
Stewart: Modern relational databases must be shared-nothing distributed SQL
“We think that again, if you were to build a relational database today with the current state of art, you would end up with a shared nothing, a SQL database that supports transactions.”
Stewart: Amazon Aurora's single master limits write scaling and creates downtime risk
“If you're, if you have a lot of rights, they're still going to a single master. They didn't rewrite the execution engine. So if that master goes down, your apps offline, if you want to scale your rights, you're going to have to get a larger and larger master m…”
Stewart: Enterprise managed cloud demand is driven by SRE hiring bottlenecks
“When we first built it, we were thinking, hey, this is for the startups. This is for the growth stage companies. But what we've seen in practice is that even the enterprises are like, we cannot hire site reliability engineers or operators fast enough to run th…”
Stewart: Dropping CS and PM requirements speeds up product manager hiring
“Because I can hire product managers a lot faster than someone that says, Hey, you already have to be a product manager or you have to have a computer science background.”
Stewart: CockroachDB scales reads and writes arbitrarily across supported PostgreSQL features
“We don't have full Postgres compatibility today, but every Postgres feature we have is cloud native. It will use the full power of the cluster to serve your queries and we can scale writes arbitrarily. We can scale reads arbitrarily.”
Stewart: Cassandra offers fast reads but requires upfront knowledge of queries
“Cassandra can give you extremely fast reads, but it's going to come at the cost of some flexibility because for Cassandra, you have to know your query patterns ahead of time. You have to design your data for a particular set of queries.”
Stewart: Cockroach Cloud will be default way people experience CockroachDB
“Cockroach Cloud, which we believe will be the default way that people experience CockroachDB”
Stewart: Online education will drive CockroachDB adoption into mission-critical apps
“We believe that online education really is the future way that we're going to get CockroachDB into more mission critical applications.”
Stewart: Migrating to NoSQL sacrificed ACID consistency, creating major development drawbacks
“You traded scale for acid, but that's something you lost when you're moving away from the relational database. And it turned out that losing acid Was a big deal.”
Nate Stewart: Cockroach Labs product team has about 25 people
“So the product team right now is about 25 people.”
Stewart: Traditional relational databases require offline downtime for schema changes
“In traditional relational databases. You're going to have to take the app offline. You're going to have to lock a table.”
Stewart: CockroachDB presents as a single Postgres database to developers
“From the point of view of the application developer, it looks like they're talking to a single Postgres database, but it just so happens to be elastically scalable.”
Stewart: Google Spanner paper provided the foundation for CockroachDB
“With some breakthroughs in computer science, there was the Google Spanner paper that came out, and it said, hey, you can get transactions. You can have these types of guarantees in a distributed environment, and that was really the foundation for the work that…”
Stewart: Cockroach Labs lacked telemetry before building managed cloud service
“So we don't look at the data that is in the database, but you know, where are people getting stuck when they're signing up? How long is it taking them to run that first query? That's information that was completely lost to us when we were just offering the ope…”
