  title: Amazon EMR Launch a Presto Query Cluster
  summary: Create an EMR cluster with the Presto application for interactive SQL.
  description: >-
    Launches a managed Amazon EMR cluster pre-configured for interactive,
    distributed SQL analytics by installing the Presto application. The workflow
    calls RunJobFlow with the supplied cluster name, instance configuration, and
    release label, requests the Presto application, and returns the new
    cluster's JobFlowId. Every step spells out its request inline, including the
    AWS JSON protocol X-Amz-Target header, so the flow can be read and executed
    without opening the underlying OpenAPI description.
