## AI overview

The article introduces a new series on consistency models, focusing on practical details and their implementations. It distinguishes the topic from a simple strong-versus-eventual consistency trade-off and previews posts about durability, ACID, and the Dynamo model.

## Source excerpt

"Those are my consistency models, and if you don't like them... well, I have others." - Groucho Marx, quoted from memory The CAP theorem series is coming to an end. I have a few posts planned, but they will be mainly about wrapping things-up-- I hope these posts will be great, though. Anyway, here starts a new series: the consistency series. This series is about getting into some practical details about the consistency models and their implementations. You think that the trade-off is only or mainly on strong consistency vs. eventual consistency? That everything is said with "W+R" vs. "N"? Then read this series. Settling on the color may not be enough when choosing a car. Posts, in recommended reading order The posts published so far are: Eventual Consistency and Durability: shows the link between durability and consistency, and why traditional databases have the 'D' in ACID. Tells you what 'W=1' implies in the Dynamo model.
