PERF03-07 Selecting an Appropriate Kafka

  • Risk level

    Medium

  • Key strategies

    Calculate the specifications required by services based on indicators such as the production traffic, consumption traffic, aging time, and number of replicas, and select appropriate Kafka specifications.

    Specification calculation

    Min. performance-required nodes = Max.((required storage bandwidth / storage bandwidth per node), (required network bandwidth / assured network bandwidth per node))

    Min. disk-required nodes = Max.(total disk capacity / maximum disk capacity per node)

    For details about how to select specifications, see the official document.
