  title: YugabyteDB Aeon Scale Cluster
  summary: Read a cluster, submit an updated specification, and poll until it returns to ACTIVE.
  description: >-
    Vertical and horizontal scaling of a YugabyteDB Aeon cluster is performed by
    submitting an updated cluster specification. This workflow reads the current
    cluster for context, applies the new configuration (such as node count, disk
    size, or fault tolerance), and then polls the cluster until the asynchronous
    update completes and it returns to the ACTIVE state. Every step spells out
    its request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.

  summary: Apply an updated cluster specification and wait for the cluster to settle.

    Reads the current cluster, submits an updated specification to scale it, and
    polls the cluster until the update finishes and the cluster is ACTIVE again.
