**Available in:** [Cloud](https://docs.redpanda.com/cloud-data-platform/develop/connect/components/inputs/redis_streams/%20%22View%20the%20Cloud%20version%20of%20this%20component%22), Self-Managed

Pulls messages from Redis (v5.0+) streams with the XREADGROUP command. The `client_id` should be unique for each consumer of a group.

#### Common

```yml
inputs:
  label: ""
  redis_streams:
    url: "" # No default (required)
    body_key: body
    streams: [] # No default (required)
    auto_replay_nacks: true
    limit: 10
    client_id: ""
    consumer_group: ""
```

#### Advanced

```yml
inputs:
  label: ""
  redis_streams:
    url: "" # No default (required)
    kind: simple
    master: ""
    client_name: redpanda-connect
    tls:
      enabled: false
      skip_cert_verify: false
      enable_renegotiation: false
      root_cas: ""
      root_cas_file: ""
      client_certs: []
    body_key: body
    streams: [] # No default (required)
    auto_replay_nacks: true
    limit: 10
    client_id: ""
    consumer_group: ""
    create_streams: true
    start_from_oldest: true
    commit_period: 1s
    timeout: 1s
```

Redis stream entries are key/value pairs, as such it is necessary to specify the key that contains the body of the message. All other keys/value pairs are saved as metadata fields.

## [](#fields)Fields

### [](#auto_replay_nacks)`auto_replay_nacks`

Whether messages that are rejected (nacked) at the output level should be automatically replayed indefinitely, eventually resulting in back pressure if the cause of the rejections is persistent. If set to `false` these messages will instead be deleted. Disabling auto replays can greatly improve memory efficiency of high throughput streams as the original shape of the data can be discarded immediately upon consumption and mutation.

**Type**: `bool`

**Default**: `true`

### [](#body_key)`body_key`

The field key to extract the raw message from. All other keys will be stored in the message as metadata.

**Type**: `string`

**Default**: `body`

### [](#client_id)`client_id`

An identifier for the client connection.

**Type**: `string`

**Default**: `""`

### [](#client_name)`client_name`

Set the client name for the Redis connection.

Requires version 4.82.0 or later.

**Type**: `string`

**Default**: `redpanda-connect`

### [](#commit_period)`commit_period`

The period of time between each commit of the current offset. Offsets are always committed during shutdown.

**Type**: `string`

**Default**: `1s`

### [](#consumer_group)`consumer_group`

An identifier for the consumer group of the stream.

**Type**: `string`

**Default**: `""`

### [](#create_streams)`create_streams`

Create subscribed streams if they do not exist (MKSTREAM option).

**Type**: `bool`

**Default**: `true`

### [](#kind)`kind`

Specifies a simple, cluster-aware, or failover-aware redis client.

**Type**: `string`

**Default**: `simple`

**Options**: `simple`, `cluster`, `failover`

### [](#limit)`limit`

The maximum number of messages to consume from a single request.

**Type**: `int`

**Default**: `10`

### [](#master)`master`

Name of the redis master when `kind` is `failover`

**Type**: `string`

**Default**: `""`

```yaml
# Examples:
master: mymaster
```

### [](#start_from_oldest)`start_from_oldest`

If an offset is not found for a stream, determines whether to consume from the oldest available offset, otherwise messages are consumed from the latest offset.

**Type**: `bool`

**Default**: `true`

### [](#streams)`streams[]`

A list of streams to consume from.

**Type**: `array`

### [](#timeout)`timeout`

The length of time to poll for new messages before reattempting.

**Type**: `string`

**Default**: `1s`

### [](#tls)`tls`

Custom TLS settings can be used to override system defaults.

**Troubleshooting**

Some cloud hosted instances of Redis (such as Azure Cache) might need some hand holding in order to establish stable connections. Unfortunately, it is often the case that TLS issues will manifest as generic error messages such as "i/o timeout". If you’re using TLS and are seeing connectivity problems consider setting `enable_renegotiation` to `true`, and ensuring that the server supports at least TLS version 1.2.

**Type**: `object`

### [](#tls-client_certs)`tls.client_certs[]`

A list of client certificates to use. For each certificate either the fields `cert` and `key`, or `cert_file` and `key_file` should be specified, but not both.

**Type**: `object`

**Default**: `[]`

```yaml
# Examples:
client_certs:
  - cert: foo
    key: bar

# ---

client_certs:
  - cert_file: ./example.pem
    key_file: ./example.key
```

### [](#tls-client_certs-cert)`tls.client_certs[].cert`

A plain text certificate to use.

**Type**: `string`

**Default**: `""`

### [](#tls-client_certs-cert_file)`tls.client_certs[].cert_file`

The path of a certificate to use.

**Type**: `string`

**Default**: `""`

### [](#tls-client_certs-key)`tls.client_certs[].key`

A plain text certificate key to use.

> ⚠️ **CAUTION**
>
> This field contains sensitive information that usually shouldn’t be added to a configuration directly. For more information, see [Secrets](https://docs.redpanda.com/connect/configuration/secrets/).

**Type**: `string`

**Default**: `""`

### [](#tls-client_certs-key_file)`tls.client_certs[].key_file`

The path of a certificate key to use.

**Type**: `string`

**Default**: `""`

### [](#tls-client_certs-password)`tls.client_certs[].password`

A plain text password for when the private key is password encrypted in PKCS#1 or PKCS#8 format. The obsolete `pbeWithMD5AndDES-CBC` algorithm is not supported for the PKCS#8 format.

Because the obsolete pbeWithMD5AndDES-CBC algorithm does not authenticate the ciphertext, it is vulnerable to padding oracle attacks that can let an attacker recover the plaintext.

> ⚠️ **CAUTION**
>
> This field contains sensitive information that usually shouldn’t be added to a configuration directly. For more information, see [Secrets](https://docs.redpanda.com/connect/configuration/secrets/).

**Type**: `string`

**Default**: `""`

```yaml
# Examples:
password: foo

# ---

password: ${KEY_PASSWORD}
```

### [](#tls-enable_renegotiation)`tls.enable_renegotiation`

Whether to allow the remote server to repeatedly request renegotiation. Enable this option if you’re seeing the error message `local error: tls: no renegotiation`.

Requires version 3.45.0 or later.

**Type**: `bool`

**Default**: `false`

### [](#tls-enabled)`tls.enabled`

Whether custom TLS settings are enabled.

**Type**: `bool`

**Default**: `false`

### [](#tls-root_cas)`tls.root_cas`

An optional root certificate authority to use. This is a string, representing a certificate chain from the parent trusted root certificate, to possible intermediate signing certificates, to the host certificate.

> ⚠️ **CAUTION**
>
> This field contains sensitive information that usually shouldn’t be added to a configuration directly. For more information, see [Secrets](https://docs.redpanda.com/connect/configuration/secrets/).

**Type**: `string`

**Default**: `""`

```yaml
# Examples:
root_cas: |-
  -----BEGIN CERTIFICATE-----
  ...
  -----END CERTIFICATE-----
```

### [](#tls-root_cas_file)`tls.root_cas_file`

An optional path of a root certificate authority file to use. This is a file, often with a .pem extension, containing a certificate chain from the parent trusted root certificate, to possible intermediate signing certificates, to the host certificate.

**Type**: `string`

**Default**: `""`

```yaml
# Examples:
root_cas_file: ./root_cas.pem
```

### [](#tls-skip_cert_verify)`tls.skip_cert_verify`

Whether to skip server side certificate verification.

**Type**: `bool`

**Default**: `false`

### [](#url)`url`

The URL of the target Redis server. Database is optional and is supplied as the URL path.

**Type**: `string`

```yaml
# Examples:
url: redis://:6379

# ---

url: redis://localhost:6379

# ---

url: redis://foousername:foopassword@redisplace:6379

# ---

url: redis://:foopassword@redisplace:6379

# ---

url: redis://localhost:6379/1
