- class sosw.components.sns.SnsManager(**kwargs)
AWS Simple Notification System Manager helper. Requires the Role to have permissions to access SSM for requested resources, something like.
Must have a recipient specified either during initialization or later using set_recipient method. Messages received by send_message() are batched and will be actually send to SNS only during the call of commit() or during the destruction of the class.
The method doesn’t yet support batching messages for multiple recipients, so in case you try to change the recipient it automatically sends all the currently batched messages to the previous recipient.
Combines messages from self.queue and pushes them to self.recipient. Cleans the queue after that.
