advent-of-code-2020 VS grenad

Another brilliant source which I've found is https://github.com/timvisee/advent-of-code-2020. Great inspirational use of iterators there.

Cool to see the itertools approach here though :) Link to the solution I saw before

Cool! My first time on TWIR with Solving Advent of Code 2020 in under a second. Though it isn't specifically about Rust, I did use Rust.

The use of a different data structure for the low and high side of the look up table made it faster as described here.

Oh yes, did Advent of Code in under a second last december, shameless plug 😎.

I tried new inserting algorithms on the sorter to reduce the amount of time spent sorting but didn’t find anything better than that, would you have any idea? I gave up trying better inserting algorithms by declaring that doing one final in-memory sort was more effective that doing a lot of comparison to try inserting keys in the right order…

I have finalized the latest release of grenad which introduce a lookup struct called a Cursor. Grenad is a library that provides tools to sort, merge, write, and read immutable key-value pairs.

I worked on my grenad library: a library used to sort, merge, write, and read key-value pairs, used in MeiliSearch for the new indexing system. I added a lot of documentation to the crate and done a lot of improvement by reducing the amount of copied memory when merging key-value pairs.

I was wondering if you could maybe point me to any blog post regarding the segment merging? I am using my grenad library, which is a simplification of my MTBL Rust port. This is a key-value store with some useful sorter helping functions, using a merge function, some compression parameters... Works great but could maybe be improved.

I also wanted to develop an immutable key-value store with some interesting properties like compression and multi-database (like for LMDB), it is much easier to develop than LMDB, I just need to base this on something like my grenad lib plus a wrapper to support multi-databases.
