Ali Beyad b18bfd6062 Output all empty snapshot info fields if in verbose mode (#25455)
In #24477, a less verbose option was added to retrieve snapshot info via
GET /_snapshot/{repo}/{snapshots}.  The point of adding this less
verbose option was so that if the repository is a cloud based one, and
there are many snapshots for which the snapshot info needed to be
retrieved, then each snapshot would require reading a separate snapshot
metadata file to pull out the necessary information.  This can be costly
(performance and cost) on cloud based repositories, so a less verbose
option was added that only retrieves very basic information about each
snapshot that is all available in the index-N blob - requiring only one
read!

In order to display this less verbose snapshot info appropriately, logic
was added to not display those fields which could not be populated.
However, this broke integrators (e.g. ECE) that required these fields to
be present, even if empty.  This commit is to return these fields in the
response, even if empty, if the verbose option is set.

Elasticsearch REST API JSON specification

This repository contains a collection of JSON files which describe the Elasticsearch HTTP API.

Their purpose is to formalize and standardize the API, to facilitate development of libraries and integrations.

Example for the "Create Index" API:

{
  "indices.create": {
    "documentation": "http://www.elastic.co/guide/en/elasticsearch/reference/master/indices-create-index.html",
    "methods": ["PUT", "POST"],
    "url": {
      "path": "/{index}",
      "paths": ["/{index}"],
      "parts": {
        "index": {
          "type" : "string",
          "required" : true,
          "description" : "The name of the index"
        }
      },
      "params": {
        "timeout": {
          "type" : "time",
          "description" : "Explicit operation timeout"
        }
      }
    },
    "body": {
      "description" : "The configuration for the index (`settings` and `mappings`)"
    }
  }
}

The specification contains:

  • The name of the API (indices.create), which usually corresponds to the client calls
  • Link to the documentation at http://elastic.co
  • List of HTTP methods for the endpoint
  • URL specification: path, parts, parameters
  • Whether body is allowed for the endpoint or not and its description

The methods and url.paths elements list all possible HTTP methods and URLs for the endpoint; it is the responsibility of the developer to use this information for a sensible API on the target platform.
