Hey guys! Just wanted to share a tip on how to use performant Guid as primary keys in databases. Have you heard about UUID Version 7? It's here to save the day! Give it a try and let me know what you think. Happy coding! 😎💻
Here's the link to the library: https://github.com/mareek/UUIDNext

I need some help to adapt my UUID/GUID library (UUIDNext) to generate the best UUIDs for PostgreSQL, MySQL and other DBMS
I maintain a library that generate database optimized UUIDs and to investigate how UUID are stored and sorted on various databases, I need you to execute a little program that show just that (see end of post for more details).

How to use performant Guid as primary keys in databases. UUID Version 7 to the rescue!
There's a reason why, for example, this library - https://github.com/richardtallent/RT.Comb/ - uses different algorithms for PostgreSQL and for MSSQL.

Why should I map external IDs to internal IDs in my API?
You mention your ExternalId is a Guid, and your InternalId is an int - so unless you use Guids in your database correctly (more info, read for example RT.Comb) - Using ints for searching is much faster
What are some alternatives?
When comparing UUIDNext and RT.Comb you can also consider the following projects:
