Hi! I'm self-taught in programming and have never learned how to handle databases; I'm trying to run a FiveM server from this opensource code: https://github.com/SOZ-Faut-etre-Sub/SOZ-FiveM-Server and followed their explanations to migrate the database,…

For example here is the n+1 problem // 1 query to get all surveys const surveys = await db.query("SELECT * FROM surveys"); // then N queries — one per survey const results = await Promise.all( surveys.map(async (survey) => { const employee = await…

Benchmarked SQLite write performance 11 ways and the result was not what I expected. The database wasn't the bottleneck. The ORM was. Raw sqlite3.executemany hits 88K r/s. SQLAlchemy caps at 3,800.…

Data drift is one of those issues that can look small at first but take much longer to track down than expected. A common case: staging and production schemas look the same, but a few reference tables have changed.…
