kairos

kairos provides time series storage using Redis or Mongo backends. As of the 0.3.0 release, we have implemented support for Gregorian data intervals (daily, weekly, monthly, yearly) and there is a new API for Timeseries.series(). Check the README for more details.

leaderboard

leaderboard allows you to build leaderboards using Redis. The leaderboard (Ruby), leaderboard-python and leaderboard-coffeescript libraries all saw updates this week. In leaderboard 3.1.0, we added support for a members_only option when making various leaderboard requests to only return the member data and not rank or score data. This same functionality was ported to leaderboard-coffeescript 1.1.0 and leaderboard-python 2.3.0.

With the 0.3.0 release, we upgrade to kairos 0.3.0 to add support for Gregorian dates and date ranges to “/series”, added support for UNIX timestamps or parsedatetime-compatible strings for ‘start’ and ‘end’ parameters to “/series” and added support for ‘steps’ parameter to “/series”.

chai provides a very easy to use api for mocking/stubbing your python objects, patterned after the Mocha library for Ruby. In 0.3.0, expectations have been improved on by not insisting that one knows how many times an expectation will be called unless explicitly set as well as assuming any arguments on an expectation unless explicitly set. Finally we fixed stubbing properties on an instance.

kairos

kairos provides time series storage using a Redis backend. kairos is intended to replace RRD in situations where the scale of Redis is required, with as few dependencies on other packages as possible. A number of quick releases went out, but as of the 0.1.5 release, we fixed increment by integer on a Count series, added a Gauge type and fixed a bug turning relative interval definitions into integers for calculations in get() and series().

torus

torus is a service implementing the Carbon protocol to store time series data using kairos and an HTTP server to query and analyze the data. It’s a new project and compared to traditional disk stores such as RRD and Whisper, torus adds:

• abstraction on top of kairos for histograms, input and output processing
• compact storage for sparse data points
• scaling with per-schema hosting and sharding
• non-buffering semantics for aggregate processing
• consistent hashing of timestamps for ease in interleaving and interpolation
