  title: Presto Client REST Statement API
  description: 'The Presto Client REST API is the HTTP protocol used by Presto clients to

    submit SQL queries to a Presto coordinator and stream back results. Queries

    are submitted with POST /v1/statement, subsequent result pages are fetched

    by following the nextUri returned in each response, and queries can be

    cancelled by issuing DELETE on the nextUri. Session context such as user,

    catalog, schema, time zone, and language is conveyed through X-Presto-*

    request headers; coordinators echo back X-Presto-Set-* / X-Presto-Clear-*

    response headers that clients must propagate on subsequent requests.


    Supported authentication mechanisms on the coordinator include Kerberos,

    LDAP, password files, OAuth 2.0, and custom authenticators.
