  Project mention: 3 reasons to adopt Event Sourcing | dev.to | 2021-04-01

  Where's the catch, then? Well, there's a couple of catches, in fact. First of all, in a distributed setting, appending data to a log isn't that easy. First, you need to make your log distributed. Again, Kafka/Cassandra/EventStore make this possible, however, whenever you start dealing with distributed data, you‘re introducing new operational and implementation complexity.

  I went off of what I was told by the npgsql maintainer. If you have different information that proves this false I’m all ears.

• Pomelo.EntityFrameworkCore.MySql

  2 1,967 8.8 C#

  Entity Framework Core provider for MySQL and MariaDB built on top of MySqlConnector

  

  Project mention: Question about C# and MySql | reddit.com/r/csharp | 2021-02-18

  For MySQL and friends you'll need the Pomelo data provider from https://github.com/PomeloFoundation/Pomelo.EntityFrameworkCore.MySql . Turns out there's an example of using the MySQL provider about halfway down that shows how to, but it is missing the '-o Model' parameter that you'd use to get your database model into a folder called Model.

• SqlKata Query Builder

  2 1,915 5.6 C#

  SQL query builder, written in c#, helps you build complex queries easily, supports SqlServer, MySql, PostgreSql, Oracle, Sqlite and Firebird

  

  Project mention: Windyquery: A non-blocking Python PostgreSQL query builder | news.ycombinator.com | 2021-05-10

  That is basically the description of an object mapper, with all the guarantees of an object mapper :). It seems if you actually use the query builder as such, no guarantees exist.

  I'm pretty picky regarding query builders and ORM's, to the extent of having written several of them over the years, in different languages (both dynamic and strong typed, unfortunately closed-source). I'm a strong advocate of schema-first design, and usually a query builder will allow you to design your queries explicitly, but having some internal behaviors (such as string concatenation, identifier quoting and automatic in-order separation of parameters and values to be bound) taken care of. As good examples of this, I'd mention golang's goqu (https://github.com/doug-martin/goqu) and - to some extent - C# SqlKata (https://sqlkata.com/). Following my frustrations with Python ORMs, I built my own toy project, sort-of-in-beta, called rickdb (https://github.com/oddbit-project/rick_db).

  Project mention: Ask HN: What tangible benefits did you get from spending time on HN? | news.ycombinator.com | 2021-03-06

  Every so often, posts from Bruce Dawson's blog get posted here - one such post was about using Event Tracing for Windows to diagnose an issue with an NTFS lock being held causing 63 cores to idle while 1 does all the work.

  https://randomascii.wordpress.com/2019/10/20/63-cores-blocke...

  A few months later, some other people in my team were struggling to diagnose an issue in production where a legacy webapp was struggling to scale up and fully use all 64 cores of the server we needed it to run on. I stepped in to help and remembered that post I'd seen on HN. We used ETW (through Windows Performance Recorder and Windows Performance Analyzer) to profile our app and I looked into the Wait Analysis. Turns out that Entity Framework 6 uses a ReaderWriterLockSlim to guard a cache, and that particular lock performs extremely poorly under heavy contention. Heavy in our case meant that for a single page build of one of this app's "hot path" pages, this lock would be taken a few hundred thousand times. We weren't the first to discover this:

  https://github.com/dotnet/ef6/issues/1500

  What some other people in my team were struggling with for about two weeks was resolved in a single day thanks to me goofing off and reading HN. (We ultimately used a fork of EF6 that didn't suffer from this issue to solve our problem)
