Hi operators and developers,
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.
For now, I want to confirm the effect about this change of your current
deployment/products, appreciate your feedback.
