|[eclipse.org-planning-council] eclipse.org server usage patterns versus new innovative tools|
Planning Council, Cross Projects List, EMO,|
The eclipse.org IT infrastructure (cvs, svn, bugzilla, wiki, eclipsecon, etc) is designed to support current usage patterns and expected growth to those patterns. Innovation in frameworks and tools can affect those usage patterns. I think we should write up a policy for how Eclipse projects should assist the EMO in planning for usage pattern changes.
For example, our CVS system is designed around the historic usage pattern of developers syncing up with the HEAD, doing some work, then committing their changes, iterating a few times a day, maybe a dozen times a day. But what if the Team-CVS project team wanted to include a "automatically check for changes" feature in the Team-CVS code. If the automatic part ran frequently (every few minutes), this might impose a large load on the eclipse.org CVS servers and bandwidth - a dramatic change to the usage pattern. And yet we don't want to discourage innovation like this because it could be a great feature for end users.
We (the EMO) would want to be involved in design decisions so that we can understand what the usage pattern changes and their impacts will be. And we'd like to be involved in web-api design so that there are ways for us to throttle back the bandwidth/resources at critical times (e.g., the big June release and the last week before EclipseCon). For example, the hypothetical Team-CVS feature could utilize a reply code from the servers to throttle back how often it checks for updates. Etc.
