Sample MCQ Question with Detailed Explanation
Question:
What is the primary purpose of using a partition key in Apache Cassandra?
Answer Options:
To uniquely identify a row within a table
Explanation: This is not correct. While the partition key is part of the primary key and helps in identifying rows, its primary purpose is to determine the distribution of data across the nodes in the cluster.
To determine the node where the data will be stored
To speed up query performance by enabling secondary indexing
To maintain data consistency across replicas
Explanation: While the partition key helps in identifying the data’s location, consistency is managed through replication settings and consistency levels, not directly by the partition key.
To facilitate automatic failover in case of node failure
To enable efficient data compaction and storage management
Correct Answer: 2
Overall Explanation: The partition key in Apache Cassandra is crucial for determining how data is distributed across the nodes in a cluster. It ensures an even distribution, which is essential for load balancing and efficient query processing.
