Project mention: Eli Bendersky: Faster XML Stream Processing in Go | news.ycombinator.com | 2024-05-07Pretty sure the C performance would have been trivially matched by C# were it to be ported there.
While not XML (which does not see much love from the community to surprise of HN), gigabytes per second of parsing throughput are reached for CSV without sacrificing UX: https://github.com/nietras/Sep?tab=readme-ov-file#packageass...
Project mention: Show HN: My Go SQLite driver did poorly on a benchmark, so I fixed it | news.ycombinator.com | 2023-12-14The meat of the P/Invoke code is in here: https://github.com/electroly/sqlnotebook/tree/master/src/Sql...
The parent directory includes code that uses it. I'm most proud of this SQLite virtual table module that proxies queries to remote ADO.NET connections, allowing you to write joins directly between local SQLite tables and remote SQL Server tables. https://github.com/electroly/sqlnotebook/blob/master/src/Sql...
I've also got a generic virtual table module that lets me easily write table-valued functions in C#: https://github.com/electroly/sqlnotebook/blob/master/src/Sql...
The goal is to provide various "supercharged" features to base SQLite by taking advantage of all the extension points I can. I wish some went further; in particular the virtual table API doesn't "push down" enough of the original query to allow the module to avoid doing O(N+1) queries in some cases.
Also, a little self-promotion here, I've created the CSV Lint plug-in for Notepad++ to work with CSV text data files. It can reformat, validate and sort csv files, as well as convert csv to different formats including SQL. Meaning it can take a csv data file and generate INSERT INTO statements, including CREATE TABLE with the corresponding column datatypes and everything.
