Apache Cassandra 4.0, released after three years and over 1,000 bug fixes, is considered the most stable database ever released due to its relentless commitment to quality. The open-source project has seen contributions from more than 200 people, with a focus on collaboration and dedication to the community of users, developers, and enterprises. Companies like Apple, Netflix, T-Mobile, and The Home Depot are successfully running Cassandra in production, leveraging its ability to manage massive amounts of fast-moving data reliably and scalably. With innovations like Stargate and K8ssandra, the future for Apache Cassandra looks promising as it continues to expand its ecosystem while maintaining its open-source foundation.
