v0.17.0

Dragonfly v0.17.0

This is probably the last version before the 1.0 GA release.

• Multiple performance & stability improvements around transactions and lua scripts.
• helm scripts support password-based authentication
• Improve memory introspection tooling to be able to track memory usage in production easier
• Switched to dragonfly-specific snapshotting format (Dragonfly still supports saving/loading rdb files).
• Backport to Dragonfly lua functions that were deprecated after lua version 5.1 (getn, unpack)
• A new docs site was launched: https://dragonflydb.io/docs
• Dragonfly can now emulate cluster-mode by exposing itself as a single-shard cluster. See cluster_mode flag for more details.
• Experimental support for SADDEX/HSETEX commands that allow setting a TTL on SET/HASH members. This solves a 8-year-old feature request existing in the Redis project: redis/redis#2905

Huge thanks to all the contributors! ❤️
