I understand your concerns and the team will find a better way to deal
with the rollback, the expected result is that it won't break anyone who
are using Gnocchi or other storage backend but it means much to the
cloud providers(like OVH and us) who are still using old version
Ceilometer and relying on the API.

Does InfluxDB or Prometheus support to store samples that could be
leveraged for auditing or billing purpose? I'm not familiar with TSDB
but I got the answer NO according to the chatting with some other

I don't think the license change will affect the cloud that only uses
MongoDB as internal service backend storage unless I'm missing
