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
- Explanation: This is correct. The partition key is hashed to determine the node where the data should reside, ensuring even data distribution and load balancing across the cluster.
- To speed up query performance by enabling secondary indexing
- Explanation: This is incorrect. Secondary indexing is a separate feature and not directly related to the purpose of the partition key.
- 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
- Explanation: This is incorrect. Failover mechanisms are handled by the replication strategy and consistency levels in Cassandra.
- To enable efficient data compaction and storage management
- Explanation: This is not the primary role of the partition key. Data compaction and storage management are part of Cassandra’s background processes.
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.
