-- 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.
