What is CAP theorem used for?
The CAP theorem, originally introduced as the CAP principle, can be used to explain some of the competing requirements in a distributed system with replication. It is a tool used to make system designers aware of the trade-offs while designing networked shared-data systems.
How is CAP consistency is different from acid consistency explain with any scenario?
ACID consistency is all about database rules. When systems offer some or all of the ACID properties across a cluster, CAP consistency becomes more involved. If a system offers repeatable reads, compare-and-set or full transactions, then to be CAP consistent, it must offer those guarantees at any node.
Why CAP theorem is most important in NoSQL systems?
It is very important to understand the limitations of NoSQL database. CAP theorem or Eric Brewers theorem states that we can only achieve at most two out of three guarantees for a database: Consistency, Availability and Partition Tolerance. …
What is CAP theorem how it is different from acid properties?
The CAP theorem asserts that any distributed system that uses data from different locations can have at most two of the three desirable CAP properties [5]. Traditional ACID properties are weakened, but not completely dropped, in order to optimize CAP properties.
What is CAP theorem how it is applicable to NoSQL systems?
According to the CAP theorem, there are limitations for the NoSQL database. Against three guarantees of a database, only two can be achieved — consistency, availability and partition tolerance. The CAP theorem is applied to a distributed system where only two desired characteristics will be delivered out of three.
