Yes this concerns me too, and even if we workaround the issue by adding 
Ceilo API back, I'd like to have a long-term plan to solve this issue. 
It seems there are several options on the table (including integrating 
Monasca and Ceilometer into a single stack, and other big-bang 
replacements) but it's never a one-for-one comparison as the solutions 
seem to address slightly disjoint problem spaces.

I'd like to hear from more Ceilometer users. What are they using 
Ceilometer for, and what long-term plans would be acceptable. There is a 
trade-off between adopting short-term workarounds that reintroduce 
performance issues vs. undergoing a complex migration to the "right" way 
of fixing this. Like for example there is little point in pushing 
Monasca/Ceilometer stack integration if most users say, like Catalyst 
Cloud seems to say, that they would rather have a slow performing 
Ceilometer API back.

Legacy API?
