About Apache Cassandra Assessment Test

An Apache Cassandra Assessment Test evaluates candidates for their proficiency in working with Apache Cassandra, a highly scalable and distributed NoSQL database known for its performance, fault tolerance, and linear scalability. Cassandra is widely used for managing large volumes of structured and semi-structured data across multiple nodes in a distributed cluster.

An Apache Cassandra Assessment Test evaluates candidates for:

  1. Cassandra Data Modeling: Understanding of Cassandra's data modeling principles, including denormalization, partition keys, clustering keys, and designing tables for efficient read and write operations.
  2. Query Language (CQL): Proficiency in writing queries using Cassandra Query Language (CQL) to perform CRUD operations, filter data, and execute batch operations against Cassandra databases.
  3. Data Distribution and Replication: Knowledge of Cassandra's partitioning and replication strategies to ensure data distribution across nodes, fault tolerance, and high availability in distributed environments.
  4. Consistency Levels: Understanding of Cassandra's consistency levels and their impact on data consistency, availability, and performance in distributed read and write operations.
  5. Secondary Indexes: Familiarity with creating and using secondary indexes in Cassandra to support efficient querying of non-primary key columns.
  6. Data Compression and Compaction: Knowledge of Cassandra's data compression and compaction mechanisms to optimize storage space, reduce disk I/O, and improve read/write performance.
  7. Tuning and Optimization: Ability to tune and optimize Cassandra cluster settings, memory configurations, compaction strategies, and caching options for optimal performance and resource utilization.
  8. Data Backup and Recovery: Understanding of Cassandra's backup and restore procedures, snapshot management, and disaster recovery strategies to ensure data durability and resilience against failures.
  9. Monitoring and Alerting: Familiarity with Cassandra monitoring tools and techniques for tracking cluster health, performance metrics, and diagnosing issues to ensure proactive maintenance and timely intervention.
  10. Security Best Practices: Awareness of Cassandra security features, authentication mechanisms, authorization roles, and encryption options to secure data at rest and in transit and comply with regulatory requirements.
  11. Integration and Tooling: Experience with integrating Cassandra databases with other data storage systems, ETL tools, monitoring platforms, and third-party applications to support data pipelines and analytics workflows.
  12. Schema Design Best Practices: Knowledge of Cassandra schema design best practices, including data modeling for time series data, wide rows, and avoiding hotspots and tombstones to optimize performance and scalability.

Overall, our Apache Cassandra Assessment Test evaluates candidates' knowledge, skills, and experience in designing, deploying, and managing Apache Cassandra databases, providing valuable insights into their proficiency in working with this NoSQL technology.
