Hey Martin, I'm a huge fan of LogicBlox and RelationalAI, and the research done at both had a huge impact on me as an undergrad! While you're here, could you provide some insight on why you folks went with arbitrary width tuples f

> Joins are not even a thing in graph databases; being able to directly query across edges obviates the entire concept. Nah, you do need joins if you don't only want to walk the graph from some well known roots. E.g. queries about p

Yet a relational database in 5th normal form is equivalent to a RDF-Like first order Triple graph. A lot of network databases store graphs as pointer-bogs which are hard to process and query, but that does not diminish the virtues of the gr

Well, still. Columnar and document stores still profit from performing joins under their hood. Whenever you are combining two partial query results into a coherent whole answer you need to perform some form of join. For example you could vi

When you push a package to crates.io, docs.rs will do a static analysis of this package and its dependencies and try its best to create meaningful links between the traits and implementing types. The issue is that it is quite common to have

There is a fundamental limit to that though, based on how complex rust is in a multitude of domains. From macros to types, all that stacked complexity makes amdahls law eat you alive. And it has real world implications too. Documentation c

I'm aware that it's zero-runtime-cost-abstractions, but that's not what sticks with non system devs when they read rusts "marketing material" (blog posts, talks, e.t.c.)

Even though this is awesome as it affects everything using the LLVM toolchain, I fear that for Rust, percentages won't suffice. Rust needs multi X speedups. Rusts zero cost abstractions aren't free at all, you pay with compile tim

Since you double the table size after failing to insert/displace above a constant threshhold, e.g. 8. You have O(1) insert performance. You don't need to rehash the table either, you can add additional hash functions on each grow,
