alt Hacker NewsI call BS on those Rust 10-100x claims. Rust and Java are roughly equal in performance. It is just that there are a lot of old NoSQL frameworks in Java which are trash. I also checked out those companies, some of which are doing interesting stuff. None claim things are 100x faster because of Rust. You just hurt your credibility when you say such clearly false things. That's how you end up with a Hadoop cluster which is 236x slower than a batch script.
PS None of the companies you linked seem to be using a datapath architecture which is the key to the highest level of performance
It wasn’t my intention to say “this stuff is 100x faster because rust”. DuckDB is C++. My intention was to draw distinction between the Java/Hadoop era of cluster and data systems, and the 2020s era of cluster and data systems, much of which has designs informed by stuff like this article / “Scalability but at what COST?”. I guess instead of “faster” I should say “more efficient”.
For example, the Kafka ecosystem tends to use Avro as the data transfer serialization, which needs a copy/deserialization step before it can be used in application logic. Newer stream systems like Timely tend to use zero-copy capable data transfer formats (timely’s is called Abomination) but it’s the same idea in CapnProto or Flatbuffers - it’s infinity faster to not copy the data as you decode! In my experience this kind of approach is more accessible in systems languages like C++ or Rust, and harder to do in GC languages where the default approach to memory layout and memory management is “don’t worry about it.”
