Apache Cassandra FAQs
What is Apache Cassandra?
Apache Cassandra is an open-source, distributed NoSQL database designed for handling large volumes of structured and unstructured data. It offers high scalability, fault tolerance, and fast data processing, making it ideal for real-time applications.
What makes Cassandra different from relational databases?
Cassandra differs from relational databases by using a NoSQL, schema-less data model, distributed architecture, and horizontal scalability. Unlike RDBMS, it is optimized for handling massive data workloads with minimal latency.
What are the key features of Apache Cassandra?
Cassandra’s key features include fault tolerance, high availability, tunable consistency, horizontal scalability, flexible schema, and exceptional write performance.
What is a keyspace in Apache Cassandra?
A keyspace in Cassandra is equivalent to a database in RDBMS. It is the top-level namespace that contains tables, replication settings, and other configurations.
How does Cassandra ensure fault tolerance?
Cassandra ensures fault tolerance through data replication. Data is automatically replicated across multiple nodes and data centers, allowing operations to continue even if some nodes fail.
What is tunable consistency in Cassandra?
Tunable consistency allows users to control the level of consistency for read and write operations. Options range from eventual consistency (faster but less strict) to strong consistency (slower but stricter).
How does Apache Cassandra handle data replication?
Cassandra uses replication strategies like SimpleStrategy and Network Topology Strategy to replicate data across nodes and data centers, ensuring high availability and fault tolerance.
What is the purpose of partitioning in Cassandra?
Partitioning in Cassandra distributes data across nodes based on a partition key. This ensures even data distribution and improves read and write performance.
What is Cassandra Query Language (CQL)?
CQL is the query language used in Cassandra, similar to SQL but optimized for NoSQL operations. It allows users to perform data queries and schema definitions.
What are the different consistency levels in Cassandra?
Cassandra offers multiple consistency levels, including ANY, ONE, QUORUM, and ALL. These levels define how many nodes must acknowledge a read or write operation before it is considered successful.
What are secondary indexes in Cassandra?
Secondary indexes in Cassandra allow querying non-primary key columns. However, they can impact performance and should be used cautiously for low-cardinality fields.
Can Cassandra be used for time-series data?
Yes, Cassandra is highly suited for time-series data. Its write-optimized architecture and support for time-based partitioning make it ideal for IoT, logs, and monitoring systems.
What is compaction in Cassandra?
Compaction in Cassandra is the process of merging SSTables to optimize storage and improve read performance. It helps remove tombstones (deleted data markers) and reorganize data.
How does Cassandra handle schema changes?
Cassandra supports dynamic schema changes. You can add or modify columns without downtime, making it flexible for evolving application requirements.
What industries benefit most from Apache Cassandra?
Industries like finance, healthcare, telecommunications, IoT, social media, retail, and gaming benefit significantly from Cassandra’s ability to handle large-scale, real-time data processing.

About Apache Cassandra Certification
Apache Cassandra is an open-source, distributed NoSQL database management system designed to handle massive amounts of data across multiple servers. Known for its exceptional scalability, high availability, and fault tolerance, Cassandra is an ideal solution for businesses that need to process and store data in real time, regardless of size or complexity.
Key Features of Apache Cassandra
Distributed Architecture
Cassandra’s distributed nature ensures that data is spread evenly across all nodes in a cluster. Each node is equal, eliminating single points of failure and ensuring seamless scalability.
High Availability
Designed to provide continuous availability, Cassandra uses a replication mechanism to duplicate data across multiple nodes. This ensures that data remains accessible even during hardware failures or network issues.
Linear Scalability
Cassandra allows for linear scaling by simply adding more nodes to the cluster. This ensures consistent performance even as data volumes grow exponentially.
Flexible Data Model
Its schema-less architecture supports structured, semi-structured, and unstructured data. Cassandra uses a column-family-based data model that provides flexibility for managing different data types.
Write-Optimized Performance
With its unique architecture, Cassandra excels at write-heavy workloads. It efficiently handles high-velocity data streams without compromising performance.
Built-in Data Replication
Cassandra replicates data across multiple nodes and data centers, providing fault tolerance and the ability to serve data from the nearest location to minimize latency.
Tunable Consistency
Users can configure the level of consistency required for operations, ranging from eventual consistency to strong consistency, depending on the use case.
Use Cases of Apache Cassandra
Real-Time Analytics
Cassandra’s ability to handle high-velocity data streams makes it an excellent choice for real-time analytics in industries like finance, e-commerce, and IoT.
