Subscription
The `AWS::Logs::SubscriptionFilter` resource specifies a subscription filter and associates it with the specified log group. Subscription filters allow you to subscribe to a real-time stream of log events and have them delivered to a specific destination. Currently, the supported destinations are:
An Amazon Kinesis data stream belonging to the same account as the subscription filter, for same-account delivery.
A logical destination that belongs to a different account, for cross-account delivery.
An Amazon Kinesis Firehose delivery stream that belongs to the same account as the subscription filter, for same-account delivery.
An LAMlong function that belongs to the same account as the subscription filter, for same-account delivery. There can be as many as two subscription filters associated with a log group.
