Elastic Cloud Serverless projects are autoscaled environments, fully managed by Elastic and available on Elastic Cloud.

Availability

  • Generally available

    This functionality is generally available and ready for production usage.

Serverless interfaces and procedures might differ from classic Elastic Stack deployments.

Stack

The Elastic Stack includes Elastic's core products such as Elasticsearch, Kibana, Logstash, and Beats.

Availability

  • Generally available

    This functionality is generally available and ready for production usage.

Unless stated otherwise on the page, this functionality is available when your Elastic Stack is deployed on Elastic Cloud Hosted, Elastic Cloud Enterprise, Elastic Cloud on Kubernetes, and self-managed environments.

This documentation corresponds to the latest patch available for each minor version. If you're not using the latest patch, check the release notes for changes.

Using the example from the previous section, one can continue to the next page by sending back the cursor field. In the case of CSV, TSV and TXT formats, the cursor is returned in the Cursor HTTP header.

JSON
POST /_sql?format=json
{
  "cursor": "sDXF1ZXJ5QW5kRmV0Y2gBAAAAAAAAAAEWYUpOYklQMHhRUEtld3RsNnFtYU1hQQ==:BAFmBGRhdGUBZgVsaWtlcwFzB21lc3NhZ2UBZgR1c2Vy9f///w8="
}

Which looks like:

JSON
{
  "rows" : [
    ["Dan Simmons",        "Hyperion",             482,  "1989-05-26T00:00:00.000Z"],
    ["Iain M. Banks",      "Consider Phlebas",     471,  "1987-04-23T00:00:00.000Z"],
    ["Neal Stephenson",    "Snow Crash",           470,  "1992-06-01T00:00:00.000Z"],
    ["Frank Herbert",      "God Emperor of Dune",  454,  "1981-05-28T00:00:00.000Z"],
    ["Frank Herbert",      "Children of Dune",     408,  "1976-04-21T00:00:00.000Z"]
  ],
  "cursor" : "sDXF1ZXJ5QW5kRmV0Y2gBAAAAAAAAAAEWODRMaXBUaVlRN21iTlRyWHZWYUdrdw==:BAFmBmF1dGhvcgFmBG5hbWUBZgpwYWdlX2NvdW50AWYMcmVsZWFzZV9kYXRl9f///w8="
}

Note that the columns object is only part of the first page.

You’ve reached the last page when there is no cursor returned in the results. Like Elasticsearch’s scroll, SQL may keep state in Elasticsearch to support the cursor. Unlike scroll, receiving the last page is enough to guarantee that the Elasticsearch state is cleared.

To clear the state earlier, use the clear cursor API:

JSON
POST /_sql/close
{
  "cursor": "sDXF1ZXJ5QW5kRmV0Y2gBAAAAAAAAAAEWYUpOYklQMHhRUEtld3RsNnFtYU1hQQ==:BAFmBGRhdGUBZgVsaWtlcwFzB21lc3NhZ2UBZgR1c2Vy9f///w8="
}

Which will like return the

JSON
{
  "succeeded" : true
}
