## Middlewares

In bindings configuration, KubeMQ Bridges supports middleware setting for each pair of source and target bindings.

These properties contain middleware information settings as follows:

### Logs Middleware

KubeMQ Bridges supports level based logging to console according to as follows:

| Property   | Description       | Possible Values                           |
| ---------- | ----------------- | ----------------------------------------- |
| log\_level | log level setting | "debug","info","error"                    |
|            |                   | "" - indicate no logging on this bindings |

An example for only error level log to console:

```yaml
bindings:
  - name: sample-binding 
    properties: 
      log_level: error
    sources:
    ......
```

### Retry Middleware

KubeMQ Bridges supports Retries' target execution before reporting of error back to the source on failed execution.

Retry middleware settings values:

| Property                         | Description                                           | Possible Values                             |
| -------------------------------- | ----------------------------------------------------- | ------------------------------------------- |
| retry\_attempts                  | how many retries before giving up on target execution | default - 1, or any int number              |
| retry\_delay\_milliseconds       | how long to wait between retries in milliseconds      | default - 100ms or any int number           |
| retry\_max\_jitter\_milliseconds | max delay jitter between retries                      | default - 100ms or any int number           |
| retry\_delay\_type               | type of retry delay                                   | "back-off" - delay increase on each attempt |
|                                  |                                                       | "fixed" - fixed time delay                  |
|                                  |                                                       | "random" - random time delay                |

An example for 3 retries with back-off strategy:

```yaml
bindings:
  - name: sample-binding 
    properties: 
      retry_attempts: 3
      retry_delay_milliseconds: 1000
      retry_max_jitter_milliseconds: 100
      retry_delay_type: "back-off"
    sources:
    ......
```
