efficient measures post api

[gordon chung]

just to put to paper, we discussed a new endpoint for highly 'efficient' posting of measures. currently we post json in rather verbose way {timestamp: <time>, value: <value>},.... this works fine but if we didn't have to do so much parsing it could be even better.

possibly something like some binary serialized epochtime:value pair.

When we are using ceilometer and gnocchi to store measure, I found querying metric and storing data will cost a lot time ,especially when a batch data is coming , which will cost a lot time to query metric and update metric.

e.g. when batch size is 50, the worst situation is querying metric costs about 15 seconds , it is not efficient.

I assume that could we use something like message queue to buffer measure, or some other way to reduce time cost by storing measures .

Querying has no relationship whatsoever with the size of incoming batch.
Can you be more precise about what you do exactly yxu?
