AggregateElasticSearchView

This view is an aggregate of ElasticSearchViews. The view itself does not create any index, but it references the already existing indices of the linked ElasticSearchViews.

Note

From Delta version 1.5.0, AggregateElasticSearchView can point to other AggregateElasticSearchViews.

When performing queries on the _search endpoint, this view will make use of the multi-index query capabilities of ElasticSearch in order to select the indices of every view present on this aggregate view.

If the caller does not have the permission views/query (or from v1.5, the user-defined permission) on all the views defined on the aggregated view, only a subset of indices (or none) will be selected, respecting the defined permissions.

Aggregate ElasticSearchView

Payload

{
  "@id": "{someid}",
  "@type": "AggregateElasticSearchView",
  "views": [ 
    {
        "project": "{project}",
        "viewId": "{viewId}"
    },
    ...
  ]
}

where…

  • {project}: String - The project, defined as {org_label}/{project_label}, where the {viewId} is located.
  • {viewId}: Iri - The view @id value to be aggregated.

Create using POST

POST /v1/views/{org_label}/{project_label}
  {...}

The json payload:

  • If the @id value is found on the payload, this @id will be used.
  • If the @id value is not found on the payload, an @id will be generated as follows: base:{UUID}. The base is the prefix defined on the resource’s project ({project_label}).

Create using PUT

This alternative endpoint to create a view is useful in case the json payload does not contain an @id but you want to specify one. The @id will be specified in the last segment of the endpoint URI.

PUT /v1/views/{org_label}/{project_label}/{view_id}
  {...}

Note that if the payload contains an @id different from the {view_id}, the request will fail.

Update

This operation overrides the payload.

In order to ensure a client does not perform any changes to a resource without having had seen the previous revision of the view, the last revision needs to be passed as a query parameter.

PUT /v1/views/{org_label}/{project_label}/{view_id}?rev={previous_rev}
  {...}

… where {previous_rev} is the last known revision number for the view.

Deprecate

Locks the view, so no further operations can be performed.

Deprecating a view is considered to be an update as well.

Note

Deprecating a view makes the view not searchable.

DELETE /v1/views/{org_label}/{project_label}/{view_id}?rev={previous_rev}

… where {previous_rev} is the last known revision number for the view.
