Pops messages from the beginning of a Redis list using the BLPop command.

## Fields

### `url`

The URL of the target Redis server. Database is optional and is supplied as the URL path. The scheme `tcp` is equivalent to `redis`.


Type: `string`  
Default: `"tcp://localhost:6379"`  

```yaml
# Examples

url: :6397

url: localhost:6397

url: redis://localhost:6379

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

url: redis://localhost:6379/1

url: redis://localhost:6379/1,redis://localhost:6380/1
```

### `kind`

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


Type: `string`  
Default: `"simple"`  

```yaml
# Examples

kind: simple

kind: cluster

kind: failover
```

### `master`

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


Type: `string`  
Default: `""`  

```yaml
# Examples

master: mymaster
```

### `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.enabled`

Whether custom TLS settings are enabled.


Type: `bool`  
Default: `false`  

### `tls.skip_cert_verify`

Whether to skip server side certificate verification.


Type: `bool`  
Default: `false`  

### `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`.


Type: `bool`  
Default: `false`  
Requires version 3.45.0 or newer  

### `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.


Type: `string`  
Default: `""`  

```yaml
# Examples

root_cas: |-
  -----BEGIN CERTIFICATE-----
  ...
  -----END CERTIFICATE-----
```

### `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.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: `array`  
Default: `[]`  

```yaml
# Examples

client_certs:
  - cert: foo
    key: bar

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

### `tls.client_certs[].cert`

A plain text certificate to use.


Type: `string`  
Default: `""`  

### `tls.client_certs[].key`

A plain text certificate key to use.


Type: `string`  
Default: `""`  

### `tls.client_certs[].cert_file`

The path to a certificate to use.


Type: `string`  
Default: `""`  

### `tls.client_certs[].key_file`

The path of a certificate key to use.


Type: `string`  
Default: `""`  

### `key`

The key of a list to read from.


Type: `string`  
Default: `"benthos_list"`  

### `timeout`

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


Type: `string`  
Default: `"5s"`
