Refactoring-Summary VS sortedcontainers

I find that reading books rather than code tends to be more helpful in terms of finding good takes on what clean code is -- more specifically books on refactoring or specific language-related features (like 'Effective Java' or 'Fluent Python'). The issue with just reading code is that many times - you'll miss out on why the author chose to use the expression or abstractions which they chose to use. Reading a book at least takes you through author's thought process. For an alternative - you could always browse repositories which contain notes on refactoring as well like this one (which does a good job summarizing some of the key principles from Fowler's book on refactoring):

If you like Python, the library sortedcontainers as a clear, well documented, yet short source code that is a joy to read for a non trivial problem:

https://github.com/grantjenks/python-sortedcontainers/blob/m...

See for yourself. Looks like sortedset uses sortedlist under the hood, which itself uses a list of lists under the hood.

You could use http://www.grantjenks.com/docs/sortedcontainers/ instead!

Even the Gentoo package repository manages fine with a two-level hierarchy. There's also a Python library, sortedcontainers, that suggests two-level trees are pretty good at any reasonable human-scale (and beyond), even while fixed-arity trees are asymptotically optimal.

It's a good question and to be accurate, depending on the benchmark, Mongita is about the same speed at SQLite to several-times slower.

There is less happening algorithmically than you would think. Where the tricky slow bits do exist, they have largely fallen into the happy-path of fast data structures in the Python language/stdlib. I also use sortedcontainers for indexes which helped quite a bit (http://www.grantjenks.com/docs/sortedcontainers/).

If you're curious, the benchmark code is in the repo: https://github.com/scottrogowski/mongita/blob/master/benchma...

I’d like to add sortedcontainers. I use it all the time. It basically does what it says on the tin. Other than the SortedList, the fact that the container is sorted only comes into play when you iterate over it or perform a bisect left/right.
