RoaringBitmap Extension for PostgreSQL (github.com/ChenHuajun)

Nice project. Roaring bitmaps can be very effective for fast set operations, so having them inside Postgres is interesting. I’d be curious to see real benchmarks though. If anyone has tried this on larger datasets, your experience would be good to hear.

Nice work. Roaring bitmaps fit a sweet spot for fast set operations with good compression, so seeing them brought into PostgreSQL is genuinely interesting. The fact that it plugs into native types instead of reinventing the wheel is a big plus. I would love to see real-world benchmarks. In theory this should outperform intarray and some GIN setups for certain cardinalities, but actual production numbers often look different. If anyone has tried this with large tables or event-tracking workloads, your results would be great to learn from.

looks like a fun book but just be forewarned real compiler engineering is nothing like what's covered there.

Real compiler engineering covers a lot of ground. This book is an intro to it, not the whole everything. No need to posture about it.

Any recommendation for a more realistic book? I think hacking GCC/LLVM can be pretty challenging, but hey they are real, production-grade compilers and not just typical academic projects.

there are no good modern compiler books - everything that's been written down pales in comparison to what GCC/LLVM really involve. recently i found Engineering a Compiler by Cooper and Torczon when reviewing/prepping for interviews - it wasn't bad . also there's now LLVM Code Generation by Quentin Colombet but that's basically a code walk-through of LLVM (it doesn't cover any of the algos). and it was probably out of the date the second it got published lol (not really but maybe). the truth is that trying to learn how to build a compiler from a single book is like trying to learn how to build a skyscraper from a single book.
