Multi-Database Support in DuckDB
We have some of this functionality in Presto (https://github.com/prestodb/presto), but it takes fair bit of work to implement it for all the different backends.

Rust std:fs slower than Python
Note that glibc has a similar problem in multithreaded contexts. It strands unused memory in thread-local pools, which grows your memory usage over time like a memory leak. We got lower memory usage that didn't grow over time by switching to jemalloc.
Example of this: https://github.com/prestodb/presto/issues/8993

Ask HN: What are some SQL transpilers?
SQLGlot is a really awesome tool that can. transpile SQL to various dialects -- https://news.ycombinator.com/item?id=31981568. What are some other SQL transpilers? I believe Presto (https://github.com/prestodb/presto) includes one, but what are others?

Memoization in Cost-based Optimizers
You may find a similar design in many production-grade heuristic optimizers. In our previous blog post about Presto, we discussed the Memo class that manages such references. In Apache Calcite, the heuristic optimizer HepPlanner models node references through the class HepRelVertex.
