Dragonfly 2.0 released with lower connection and serialization overhead

Infrastructure confirmed

  • Sources: primary
  • Summary: The release reduces per-connection and serialization overhead, adds loading of Valkey 9 RDB files, and makes defragmentation limits configurable. Dragonfly remains under the Business Source License 1.1 rather than an open-source license.
  • Why it matters: Valkey 9 RDB loading removes a migration step for operators moving off Redis or Valkey, with the license terms unchanged.
