 module Aws::MediaLive
+  # Waiters are utility methods that poll for a particular state to occur
+  # on a client. Waiters can fail after a number of attempts at a polling
+  # interval defined for the service client.
+  #
+  # For a list of operations that can be waited for and the
+  # client methods called for each operation, see the table below or the
+  # {Client#wait_until} field documentation for the {Client}.
+  #
+  # # Invoking a Waiter
+  # To invoke a waiter, call #wait_until on a {Client}. The first parameter
+  # is the waiter name, which is specific to the service client and indicates
+  # which operation is being waited for. The second parameter is a hash of
+  # parameters that are passed to the client method called by the waiter,
+  # which varies according to the waiter name.
+  #
+  # # Wait Failures
+  # To catch errors in a waiter, use WaiterFailed,
+  # as shown in the following example.
+  #
+  #     rescue rescue Aws::Waiters::Errors::WaiterFailed => error
+  #       puts "failed waiting for instance running: #{error.message}
+  #     end
+  #
+  # # Configuring a Waiter
+  # Each waiter has a default polling interval and a maximum number of
+  # attempts it will make before returning control to your program.
+  # To set these values, use the `max_attempts` and `delay` parameters
+  # in your `#wait_until` call.
+  # The following example waits for up to 25 seconds, polling every five seconds.
+  #
+  #     client.wait_until(...) do |w|
+  #       w.max_attempts = 5
+  #       w.delay = 5
+  #     end
+  #
+  # To disable wait failures, set the value of either of these parameters
+  # to `nil`.
+  #
+  # # Extending a Waiter
+  # To modify the behavior of waiters, you can register callbacks that are
+  # triggered before each polling attempt and before waiting.
+  #
+  # The following example implements an exponential backoff in a waiter
+  # by doubling the amount of time to wait on every attempt.
+  #
+  #     client.wait_until(...) do |w|
+  #       w.interval = 0 # disable normal sleep
+  #       w.before_wait do |n, resp|
+  #         sleep(n ** 2)
+  #       end
+  #     end
+  #
+  # # Available Waiters

+  # The following table lists the valid waiter names, the operations they call,
+  # and the default `:delay` and `:max_attempts` values.
