Dragonfly As Redis Alternative Adds Multi-Tenancy & Alpha Level SSD Data Tiering

Dragonfly 1.21 released today as the newest version of this modern, drop-in replacement to Redis and Memcached. This performance-optimized in-memory data store has added a few interesting features with the new release.

Last year with Dragonfly 1.13 it added experimental SSD-based data tiering as another means of helping to boost the performance. With today's Dragonfly 1.21 release the SSD data tiering is now treated as alpha level. The "--prefix some/path/basename" option can be used for leveraging the SSD data tiering with this otherwise in-memory data store.

Dragonfly 1.21 also adds initial support for multi-tenant deployments. With this new feature it's possible to create multiple, separate, and isolated namespaces within Dragonfly. Each user can be associated to a single namespace. This multi-tenant feature is currently experimental and some features like defrag and replication aren't yet supported.
