# Get the rollup index capabilities

deprecated

Availability: 6.4+

## Paths

- `GET` `/{index}/_rollup/data`

- [Api key auth](/elastic/docs-builder/docs/4371/api/doc/elasticsearch/v8/authentication#apikeyauth)
- [Basic auth](/elastic/docs-builder/docs/4371/api/doc/elasticsearch/v8/authentication#basicauth)
- [Bearer auth](/elastic/docs-builder/docs/4371/api/doc/elasticsearch/v8/authentication#bearerauth)

#### Path Parameters

- `index` (union Id | [] Id)
  Data stream or index to check for rollup capabilities.
Wildcard (`*`) expressions are supported.

## Description

Get the rollup capabilities of all jobs inside of a rollup index.
A single rollup index may store the data for multiple rollup jobs and may have a variety of capabilities depending on those jobs. This API enables you to determine:

* What jobs are stored in an index (or indices specified via a pattern)?
* What target indices were rolled up, what fields were used in those rollups, and what aggregations can be performed on each job?

## Required authorization

* Index privileges: `read`

## Response

`application/json`

Type: `map string to IndexCapabilities`

## Code Examples

#### Console

```console
GET /sensor_rollup/_rollup/data
```

#### JavaScript

```javascript
const response = await client.rollup.getRollupIndexCaps({
  index: "sensor_rollup",
});
```

#### Python

```python
resp = client.rollup.get_rollup_index_caps(
    index="sensor_rollup",
)
```

#### curl

```curl
curl -X GET "$ELASTICSEARCH_URL/sensor_rollup/_rollup/data" \
  -H "Authorization: ApiKey $ELASTIC_API_KEY"
```

#### Java

```java
client.rollup().getRollupIndexCaps(g -> g
    .index("sensor_rollup")
);
```

#### C#

```c#
var response = await client.Rollup.GetRollupIndexCapsAsync(index: new[] { "sensor_rollup" });
```

#### PHP

```php
$resp = $client->rollup()->getRollupIndexCaps([
    "index" => "sensor_rollup",
]);
```

#### Ruby

```ruby
response = client.perform_request(
  "GET",
  "/sensor_rollup/_rollup/data",
  {},
)
```

## Response Examples

#### Get rollup index capabilities response example1

A successful response from `GET /sensor_rollup/_rollup/data`. The response contains the rollup job ID, the index that holds the rolled data, and the index pattern that the job was targeting. It also shows a list of fields that contain data eligible for rollup searches. For example, you can use a `min`, `max`, or `sum` aggregation on the `temperature` field, but only a `date_histogram` on `timestamp`.

```json
{
  "sensor_rollup" : {
    "rollup_jobs" : [
      {
        "job_id" : "sensor",
        "rollup_index" : "sensor_rollup",
        "index_pattern" : "sensor-*",
        "fields" : {
          "node" : [
            {
              "agg" : "terms"
            }
          ],
          "temperature" : [
            {
              "agg" : "min"
            },
            {
              "agg" : "max"
            },
            {
              "agg" : "sum"
            }
          ],
          "timestamp" : [
            {
              "agg" : "date_histogram",
              "time_zone" : "UTC",
              "fixed_interval" : "1h",
              "delay": "7d"
            }
          ],
          "voltage" : [
            {
              "agg" : "avg"
            }
          ]
        }
      }
    ]
  }
}
