        <div>Hi operators and developers,</div>
        <div><br>
        </div>
        <div>We have support dedicated dabase for alarm data[1], that
          allow deployers to config ceilometer distributing alarm data
          to a separate database. And In liberty, we have splitted out
          the alarming service as a separate project Aodh from
          Ceilometer tree. Continue from Ceilometer implementation, we
          now support mongodb, Hbase, sqalchemy storage drivers for
          alarm data, but, we agree to deprecate the mongodb and Hbase
          support for alarm data and only keep sql. The reasons and
          advantages for this change have been described in the
          proposal[2]. we will deprecate them in this release cycle and
          try to provide data migration tool for migrating data from
          mongodb/Hbase to sql, and remove the mongodb and Hbase support
          in future O* cycle.</div>
        <div><br>
        </div>
        <div>For now, I want to confirm the effect about this change of
          your current deployment/products, appreciate your feedback.</div>
