Compare Source

Redis 8.6 Support

Added support for Redis 8.6, including new commands and features for streams idempotent production and HOTKEYS.

Smart Client Handoff (Maintenance Notifications) for Cluster

note: Pending RS version release

This release introduces comprehensive support for Redis Enterprise Cluster maintenance notifications via SMIGRATING/SMIGRATED push notifications. The client now automatically handles slot migrations by:

  • Relaxing timeouts during migration (SMIGRATING) to prevent false failures
  • Triggering lazy cluster state reloads upon completion (SMIGRATED)
  • Enabling seamless operations during Redis Enterprise maintenance windows

OpenTelemetry Native Metrics Support

Added comprehensive OpenTelemetry metrics support following the OpenTelemetry Database Client Semantic Conventions. The implementation uses a Bridge Pattern to keep the core library dependency-free while providing optional metrics instrumentation through the new extra/redisotel-native package.

Metric groups include:

  • Command metrics: Operation duration with retry tracking
  • Connection basic: Connection count and creation time
  • Resiliency: Errors, handoffs, timeout relaxation
  • Connection advanced: Wait time and use time
  • Pubsub metrics: Published and received messages
  • Stream metrics: Processing duration and maintenance notifications
