The Mitaka OpenStack mid-cycle quarterly report

[This post is based on the executive summary of the 2015-Q5 OpenStack Community Activity Report, sponsored by the OpenStack Foundation]

The October-Devember 2015 penStack Community Activity Report shows a stable growth of the OpenStack Community. As new repositories and teams keep being added, the number of projects keeps growing. On the other hand it is worth mentioning the decrease in activity during the latest quarters in project teams such as Nova, or stabilization of some others, such as Horizon or Cinder. This is a clear signal of the maturity reached by the some of the project teams in the OpenStack Foundation.

Active Core Reviewers reach a new peak

Although Git activity (changesets merged in the code base) does not show a large increase of activity, if compared to Gerrit, the development effort in the project keeps increasing. This last quarter of 2015 the number of Active Core Reviewers reached a new record of 449 different developers.

Time to merge keeps decreasing

During the third quarter of 2015, a small increase in time to merge seemed to signal a change in trend. However, this last quarter of 2015 keeps the previous decreasing trend. During this period the median time to merge a changeset into master decreased from 2.91 days down to 2.38 days.

Efficiency closing tickets decreases

It is noticeable the decrease of the relative number of tickets closed in OpenStack projects (also known as the efficiency of the ticket closing process). Previous quarters topped at about 60% of closed tickets (with respect to tickets opened during the same period), while this quarter shows a much lower 44%. This could be seen as a poor performance indicator of the project teams.

However, the efficiency closing changesets in the review system (number of changesets merged or abandoned with respect to number of new changesets being proposed for review) remains stable at around 80%.
