CAP Theorem: Consistency vs Availability
CAP Theorem: Consistency vs Availability
EasyHLD0% accepted
Explain the CAP theorem: a distributed system can guarantee at most 2 of 3 properties (Consistency, Availability, Partition Tolerance). Classify real systems (Cassandra, HBase, MySQL, Zookeeper) and discuss PACELC extension.
Approach
Explain CAP theorem and classify distributed databases as CA, CP, or AP.
Input
Cassandra - CAP classification
Output
AP: Cassandra prioritizes availability; during partition, may serve stale data; tunable consistency (ONE/QUORUM)
