CAP, PACELC and consistency models (Category Distributed Systems)
CAP, PACELC and consistency models (Rubric #DistributedSystems)
I'll be reading tonight. lecture with this name for students of Central University (It's good that I've recovered by now.). In this lecture, we will talk about the well-known in narrow circles theorems CAP and PACELC, discuss how consistency in these theorems differs from consistency in ACID, talk about how claimed guarantees are checked, and at the end of the lecture we will discuss Cassandra as an example of a distributed database with tunable consistency. Then there will be a workshop where we will try this Cassandra in practice to assess in practice how fun and interesting a truly distributed system can work. Basically, the theory is based on articles from my website system-design.space.
- CAP (Consistency, Availability, Partition tolerance)
- PACELC (if Partition then Availability or Consistency Else Latency or Consistency)
- Consistency Models and Verification of Jepsen Database Guarantees
- Cassandra
Well, for special aesthetes, you can read a funny analysis.MariaDB Galera Cluster 12.1.2" from Kyle Kingsbury (Jepsen)who came out all 3 A day ago. From the analysis it is clear that it is reckless to believe the marketing statements of database manufacturers - it is necessary to check their theses in practice:))
P.S. The image of ChatGPT turned out funny:)
