// Creates or updates a subscription filter and associates it with the specified
// log group. With subscription filters, you can subscribe to a real-time stream of
// log events ingested through PutLogEvents (https://docs.aws.amazon.com/AmazonCloudWatchLogs/latest/APIReference/API_PutLogEvents.html)
// and have them delivered to a specific destination. When log events are sent to
// the receiving service, they are Base64 encoded and compressed with the GZIP
// format. The following destinations are supported for subscription filters:
// - An Amazon Kinesis data stream belonging to the same account as the
// subscription filter, for same-account delivery.
// - A logical destination created with PutDestination (https://docs.aws.amazon.com/AmazonCloudWatchLogs/latest/APIReference/API_PutDestination.html)
// that belongs to a different account, for cross-account delivery. We currently
// support Kinesis Data Streams and Kinesis Data Firehose as logical destinations.
// - An Amazon Kinesis Data Firehose delivery stream that belongs to the same
// account as the subscription filter, for same-account delivery.
// - An Lambda function that belongs to the same account as the subscription
// filter, for same-account delivery.
//
// Each log group can have up to two subscription filters associated with it. If
// you are updating an existing filter, you must specify the correct name in
// filterName . To perform a PutSubscriptionFilter operation for any destination
// except a Lambda function, you must also have the iam:PassRole permission.
