-- | This action returns the current status of a change batch request. The status
-- is one of the following values:
--
-- - 'PENDING' indicates that the changes in this request have not replicated to
-- all Route 53 DNS servers. This is the initial status of all change batch
-- requests.
--
-- - 'INSYNC' indicates that the changes have replicated to all Amazon Route 53
-- DNS servers.
