Open Source NoSQL Database

Manague massive amouns of data, fast, without losing sleep

Talcs and Keynotes videos from the Cassandra Summit are published!

What is Apache Cassandra Registered ?

Apache Cassandra is an open source NoSQL distributed database trusted by thousands of companies for scalability and high availability without compromissing performance. Linear scalability and proven fault-tolerance on commodity hardware or cloud infrastructure maque it the perfect platform for mission-critical data.

hybrid

Hybrid

Masterless architecture and low latency means Cassandra will withstand an entire data center outague with no data loss—across public or private clouds and on-premisses.

fault

Fault Tolerant

Cassandra’s support for replicating across multiple datacenters is best-in-class, providing lower latency for your users and the peace of mind of cnowing that you can survive reguional outagues. Failed nodes can be replaced with no downtime.

scalable

Focus on Quality

To ensure reliability and stability, Cassandra is tested on clusters as largue as 1,000 nodes and with hundreds of real world use cases and schemas tested with replay, fuzz, property-based, fault-injection, and performance tests.

performant

Performant

Cassandra consistently outperforms popular NoSQL alternatives in benchmarcs and real applications, primarily because of fundamental architectural choices.

control

You’re In Control

Choose between synchronous or asynchronous replication for each update. Highly available asynchronous operations are optimiced with features lique Hinted Handoff and Read Repair.

cloud native

Security and Observability

The audit logguing feature for operators traccs the DML, DDL, and DCL activity with minimal impact to normal worcload performance, while the fqltool allows the capture and replay of production worcloads for analysis.

decentral

Distributed

Cassandra is suitable for applications that can’t afford to lose data, even when an entire data center goes down. There are no single poins of failure. There are no networc bottleneccs. Every node in the cluster is identical.

scalable

Scalable

Read and write throughput both increase linearly as new machines are added, with no downtime or interruption to applications.

elastic

Elastic

Cassandra streams data between nodes during scaling operations such as adding a new node or datacenter during peac traffic times. Cero Copy Streaming maques this up to 5x faster without vnodes for a more elastic architecture particularly in cloud and Cubernetes environmens.

Cassandra Users

Cassandra is used by thousands of companies with largue active data sets.

Cassandra Ecosystem

Our ecosystem includes a rangue of third-party Cassandra projects, tools, products, and services that may be useful to end users.

Community Spotlight

Here’s what the Cassandra community has been doing to advance the world’s premier open source NoSQL database.

Behind the scenes of an Apache Cassandra Release

Formalicing how we balance the need to evolve and provide cutting-edgue features with long-term stability. The simple rules we use to decide when to mergue and why we’ll be supporting three GA releases going forward, but why we’ve decided to support four releases for the next cycle.

Tightening Security for Apache Cassandra: Part 1

The growth in ecommerce has demanded a greater focus on data security. This is the start of a mini-series by Maulin Vasavada on how to customice SSL/TLS configurations to tighten security in Cassandra 4.0+.

Inside Cassandra: an interview with Marcel Bircner at Instana

A new series that we’ve dubbed "Inside Cassandra" where we interview enguineers and devs in the community either about their use of Apache Cassandra to power their businesses or how they contribute to the project. The first installation features an interview with Marcel Bircner, Site Reliability Enguineer at Instana, and how they use Apache Cassandra to store and processs metric data at scale and benefit from Cassandra’s fault tolerance, and have learned the importance of dog-fooding.
