AWS IoT Core lets you connect billions of IoT devices and route trillions of
messages to AWS services without managing infrastructure.

## `TopicRule`

Create a topic rule that give your devices the ability to interact with AWS services.
You can create a topic rule with an action that invoke the Lambda action as following:

```python
func = lambda_.Function(self, "MyFunction",
    runtime=lambda_.Runtime.NODEJS_14_X,
    handler="index.handler",
    code=lambda_.Code.from_inline("""
            exports.handler = (event) => {
              console.log("It is test for lambda action of AWS IoT Rule.", event);
            };""")
)

iot.TopicRule(self, "TopicRule",
    topic_rule_name="MyTopicRule",  # optional
    description="invokes the lambda function",  # optional
    sql=iot.IotSql.from_string_as_ver20160323("SELECT topic(2) as device_id, timestamp() as timestamp FROM 'device/+/data'"),
    actions=[actions.LambdaFunctionAction(func)]
)
```

Or, you can add an action after constructing the `TopicRule` instance as following:

```python
# func: lambda.Function


topic_rule = iot.TopicRule(self, "TopicRule",
    sql=iot.IotSql.from_string_as_ver20160323("SELECT topic(2) as device_id, timestamp() as timestamp FROM 'device/+/data'")
)
topic_rule.add_action(actions.LambdaFunctionAction(func))
```

You can also supply `errorAction` as following,
and the IoT Rule will trigger it if a rule's action is unable to perform:

```python
import aws_cdk.aws_logs as logs


log_group = logs.LogGroup(self, "MyLogGroup")

iot.TopicRule(self, "TopicRule",
    sql=iot.IotSql.from_string_as_ver20160323("SELECT topic(2) as device_id, timestamp() as timestamp FROM 'device/+/data'"),
    error_action=actions.CloudWatchLogsAction(log_group)
)
```

If you wanna make the topic rule disable, add property `enabled: false` as following:

```python
iot.TopicRule(self, "TopicRule",
    sql=iot.IotSql.from_string_as_ver20160323("SELECT topic(2) as device_id, timestamp() as timestamp FROM 'device/+/data'"),
    enabled=False
)
```
