The next major release of the popular data structure server is here. Redis is at the heart of so many data systems nowadays that any major release is big news but 6.0 packs in a lot of new bits and pieces that make it more robust and capable of modern workloads, including:
- Access Control Lists (ACL) for limiting what certain clients can do.
- Diskless replication on replicas.
- Threaded I/O (but Redis itself remains primarily single threaded).
- SSL/TLS support.
- A new client-server protocol, RESP3.
