The V2 summary endpoint uses a quite unconventional data format in
the response. Currently, the format is the following:
```
{"total": <number of elements in the response>,
"results": [array of arrays of data],
"columns": [array of columns]}
```
To process this, we need to find the index of a column in the column
list, and with this index, we retrieve the data in the array of data
that is found in the array of results. The proposal is to use the
following format in the response.
```
{"total": <number of elements in the response>,
"results": [array of objects/dictionary]}
```
With this new format, one does not need to consult the index of a
column to retrieve data in one of the entries. We would only need to
retrieve the data in the entry using its column name. Therefore, the
coding feels more natural. To maintain compatibility, this new format
would be only applied when an option is sent to CloudKitty via
`response_format` option.

CloudKitty
Rating as a Service component
Goal
CloudKitty aims at filling the gap between metrics collection systems like ceilometer and a billing system.
Every metrics are collected, aggregated and processed through different rating modules. You can then query CloudKitty's storage to retrieve processed data and easily generate reports.
Most parts of CloudKitty are modular so you can easily extend the base code to address your particular use case.
You can find more information on its architecture in the documentation, architecture section.
Status
CloudKitty has been successfully deployed in production on different OpenStack systems.
You can find the latest documentation on readthedocs.
Contributing
We are welcoming new contributors, if you've got new ideas, suggestions or want to contribute contact us.
You can reach us thought IRC (#cloudkitty @ oftc.net), or on the official OpenStack mailing list openstack-discuss@lists.openstack.org.
A storyboard is available if you need to report bugs.
Additional components
We're providing an OpenStack dashboard (Horizon) integration, you can find the files in the cloudkitty-dashboard repository.
A CLI is available too in the python-cloudkittyclient repository.
Trying it
CloudKitty can be deployed with devstack, more information can be found in the devstack section of the documentation.
Deploying it in production
CloudKitty can be deployed in production on OpenStack Kilo environments, for more information check the installation section of the documentation. Due to oslo libraries new namespace backward compatibility is not possible. If you want to install it on an older system, use a virtualenv.
Getting release notes
Release notes can be found in the release notes section of the documentation.
