# Enable a named stream

Availability: 9.1+

## Paths

- `POST` `/_streams/{name}/_enable`

- [Api key auth](/elastic/docs-builder/docs/4371/api/doc/elasticsearch/v9/authentication#apikeyauth)
- [Basic auth](/elastic/docs-builder/docs/4371/api/doc/elasticsearch/v9/authentication#basicauth)
- [Bearer auth](/elastic/docs-builder/docs/4371/api/doc/elasticsearch/v9/authentication#bearerauth)

#### Path Parameters

- `name` (enum StreamType)
  The stream type to enable.

Supported values include:
  - `logs`: The logs stream type.
  - `logs.otel`: The logs.otel stream type, meant for OTel-formatted data.
  - `logs.ecs`: The logs.ecs stream type, meant for ECS-formatted data.
  Values: `logs`, `logs.otel`, `logs.ecs`

## Description

Turn on the named stream feature for this cluster.

NOTE: To protect existing data, this feature can be turned on only if the cluster does not have
existing indices or data streams that match the pattern `<name>|<name>.*` for the enabled stream
type name. If those indices or data streams exist, a `409 - Conflict` response and error is
returned.

## Required authorization

* Cluster privileges: `manage`

## Query String Parameters

- `master_timeout` (string Duration · default: 30s)
  The period to wait for a connection to the master node.
If no response is received before the timeout expires, the request fails and returns an error.
- `timeout` (string Duration · default: 30s)
  The period to wait for a response.
If no response is received before the timeout expires, the request fails and returns an error.

## Response

`application/json`

- `acknowledged` (boolean)
  For a successful response, this value is always true. On failure, an exception is returned instead.
