Building Scalable Distributed Systems with Cassandra

🔑Cassandra is a peer-to-peer distributed database that ensures high availability and fault tolerance by distributing data across multiple nodes.

⚙️Cassandra uses token-based partitioning to distribute data across nodes in a cluster, allowing for easy scalability.

🔗Cassandra achieves fault tolerance and replication by storing multiple replicas of data on different nodes.

🌐Cassandra's data model is column-based, making it highly flexible and suitable for handling big data and time-series data.

🔄Cassandra provides tunable consistency levels, allowing developers to balance between strong consistency and high availability.

What is Cassandra?

—Cassandra is a highly scalable distributed database that provides high availability and fault tolerance by distributing data across multiple nodes.

How is data stored in Cassandra?

—In Cassandra, data is stored in a columnar format, allowing for flexible schema design and efficient querying of large datasets.

How does Cassandra ensure fault tolerance?

—Cassandra achieves fault tolerance by replicating data across multiple nodes, ensuring that even if a node fails, the data is still available.

Can Cassandra handle big data?

—Yes, Cassandra is designed to handle big data and can scale horizontally by adding more nodes to the cluster.

What are the advantages of using Cassandra?

—Some advantages of Cassandra include high availability, fault tolerance, scalability, and support for flexible data models.
