In the current benchmarks, I only have Kafka and rocksdb wal, will surely try to add redpanda there as well, curious how walrus would hold up against seastar based systems.
I don't see any mentions of p99 latency in the benchmark results. Pushing gigabytes per second is not that difficult on modern hardware. Doing so with reasonable latency is what's challenging. Also, instead of using custom benchmarks it's better to just use the OMB (open-messaging benchmark).
Like that Cloudflare outage from the other day? In any case, I'm sure there's good reason to believe that, as Rust gains popularity, there totally won't be proportionally more high profile issues in stuff made with it.
You could write a lot of bugs in Rust. Or in any memory-safe language. Just not some bugs. It's just that starting a non-toy project using a non-safe language today is really in the "you could, but didn't stop think if you should" category.
Fair enough, and I do appreciate Rust's contributions to the spectrum of programming language considerations. Personally I'd like to become a Zig guy, though.
There's also Fil-C BTW, and in normal C++ there are GCC or Clang (I forget which) extensions for detecting threading issues, even good old Valgrind is under-appreciated and under-used. In general one wants to adopt best practices and be proactive, rather than relying on the language to solve all problems (of course).
Redpanda claim of better performance but benchmarks showed no clear winner [3].
It will be interesting to test them together on the performance benchmarks.
I've got the feeling it's not due to programming language implementation of Scala/Java (Kafka), C++ (Redpanda) and Rust (Walrus).
It's the very architecture of Kafka itself due to the notorious head of line problem (check the top most comments [4].
