The I in ACID


Why talking about old things like ACID properties? We all know everything we need to know about that, right ? Well, I found out that even though this properties were old, well known and beautifully documented, it didn't mean people actually understood them.


I found myself repeatedly explaining to developers how transaction isolation works, what tradeoffs were made and why.

Particularly, transaction isolation and its anomalies were not commonly known and I found out developers adding extra layers in their application instead of simply adjusting their database isolation level for that particular transaction.

After explaining globally ACID properties, we’ll focus on transaction isolation, transaction isolation anomalies and in what case a developer should care about transaction isolation.
