The One Billion Row Challenge (1BRC) is a fun exploration of how far modern Java can be pushed for aggregating one billion rows from a text file. Grab all your (virtual) threads, reach out to SIMD, optimize your GC, or pull any other trick, and create the fastest implementation for solving this task!

The One Billion Row Challenge just finished. I followed the development throughout the month with great interest, and I’m truly amazed by the results. A few days (or even weeks) into the challenge, when great progress had already been made, I would never have guessed that it would be possible to bring the execution time down to 1.5s – well done!
However impressed I am with the achievements I also find the results somewhat discouraging. The code of the fastest contributions look very different from what me and my colleagues write in our daily work. To write really fast (Java) code it seems you should:
- Use Unsafe, although you know you shouldn’t
- Not use any built-in, general purpose, classes. Everything needs to be custom built for precisely the problem at hand.
- Create as few Java objects as possible, and don’t use the heap – allocate whatever memory you need off-heap.
- Exploit every low level hack imaginable.
- Use GraalVM Native Image – not just any JVM.
That’s not a recipe for writing portable concise maintainable code. It would be a very bad idea to start writing code like this, in general. We make performance/design trade-offs all the time. It’s a natural part of the craft of writing code. What I find discouraging is how far from the clean code I’d like to see the fast code is.
What we can do is to perhaps go halfway. Whenever you’ve built something using the latest and greatest high level api:s, and got it working correctly, know that it can probably be 100 times faster. Maybe, you should try to make it 10 times faster. That can probably be done without entirely destroying the cleanliness of the code.
The baseline implementation of 1BRC is not artificially slow. I can very well imagine colleagues writing that code, and leaving it like that. Possibly they would make the stream parallel. It is possible to do much better than the baseline and still have clean code. The example below demonstrates one way to do that, using tools provided with ojAlgo. It is 10 times faster than the baseline, and is still clear concise code.

ojAlgo: 16.335035291s
Just making the baseline’s stream parallel made things 3 times faster, but that’s on an 8-core machine.
The ojAlgo-based version is 10 times faster (using 8-cores). Apart from more efficient parallelism the ojAlgo-based version also uses a custom function to parse a portion of a String to a double.
So we, easily, made it 10 times faster. The 1BRC demonstrated that it is possible to make it 100 times faster, but then you have to write very different code.
