    Aiven for Valkey™ 9.0 is here

    We’ve added support for Valkey 9.0, a major release focused on high-scale performance and more granular data control. This version is particularly beneficial for users running large-scale clusters or complex data structures.

    Key highlights

    • Hash field expiration: You can now set TTLs (time-to-live) on individual fields within a single Hash key using commands like HEXPIRE and HTTL. This reduces memory overhead by allowing specific pieces of data to expire without needing to delete the entire key or split data across multiple keys.
    • Major throughput boosts:
      • Zero-copy & prefetching: Up to 40% higher throughput for pipelined requests and 20% for large responses.
      • Multipath TCP: Reduces network latency by up to 25%.

    Get started

    You can now select version 9.0 when creating a new service or upgrade your existing service directly in the Aiven Console.
