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 14 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
Merriman: JSON document models will emerge as the standard NoSQL data model
“My belief, which is opinion, is that in, in the end of these NoSQL data models, that the document-oriented model will be the one that kind of converges on for standard, and specifically JSON style, or JSON based.”
Merriman: Developers will use a few specialized database tools within 5-10 years
“My belief, I'm a little biased, but my belief is that if we kind of project out Say five years, 10 years, is that what we're gonna see is you'll have a few tools in your toolbox for databases.”
Merriman: HBase is more directly competitive with MongoDB than Hadoop
“I think Hadoop, or HBase, which is a Hadoop subproject, that's more of a, that's something that's more of an alternative or competitive with Mongo, where you would look at A versus B”
Merriman: Fast distributed transactions across hundreds of commodity servers are impossible
“If we have a thousand server cluster running on commodity hardware, on a commodity network, and you want to touch data and mutate it that's on 600 servers, and then you want to commit that all or nothing with isolation and option to roll it back, and you want …”
Merriman: NoSQL databases omit distributed joins to enable horizontal scaling
“Distributed joins is a hard problem, so the solution that's been chosen by both us with Mongo and the other NoSQL products is to say, you know, we're not going to do joins”
Merriman: Open source causes revenue compression relative to proprietary software
“You are going to get some revenue compression, right, by being open source versus not open source if you have the same number of users, right?”
Merriman: Startup founders are underweighting B2B enterprise opportunities
“He's right. So I think there is an underweighting of activity on B to B because there's plenty of opportunity there.”

Merriman: SNMP support is MongoDB's only non-free subscriber feature currently
“Like, I think the only thing in the subscriber edition right now that, that, that is non-free is SNMP support, for example.”
Merriman: MongoDB only supports single-document ACID transactions
“What we do currently in Mongo is we do these little microtransactions, which sort of, say, give you ACID properties, but only on a single document at a time, right? Because a single JSON document lives on one and only shard in a Mongo cluster at a given point …”
Merriman: Modifying Postgres wouldn't deliver 10gen's desired architecture
“We looked at the traditional stuff and we thought, well, you know, could we take something, can we take Postgres and start changing, you know, changing code and make something we like? And we felt like we would never, Land where we wanted to get to if we did t…”
Merriman: MongoDB 2.2 eliminates global read-write lock to improve concurrency
“Historically in Mongo, sort of the concurrency in a single MongoD process on a single server has been suboptimal. And, ah, between servers it's been good, but inside a single server it needed a lot of work. So there was a global reader-irelock, which has been …”
