Re: [cross-project-issues-dev] Retiring the UDC and removing it from the simultaneous release...


I briefly proposed to Ian a few months back that we look to redesign
UDC to use Google Analytics in place of the UDC backend. In fact,
we're experimenting with this in MOTODEV Studio for an upcoming

Would it make sense to have this discussion in a larger group? As a
product manager of a product based on Eclipse, I would like to know
what features my users find the most compelling. We tried with UDC,
but I think GA might give the type of statistics that I want to see.
To be honest, if there's enough interest in this, we could donate the

>> What if instead of gathering "everything and nothing in particular" (tm), the UDC became an opt-in mechanism where plug-in authors from could decide to monitor a specific aspect of their plug-ins, thus allowing them to make educated decisions about a particular functionality. For example, for p2, I would like to know how many ppl actually enable the automatic check for updates preference? To achieve this, I would explicitly tell the UDC to gather the value for the known preference key, and later on I could just do a few sql queries against the system to see the results (since the data would have been curated by explicit inclusion, there would not be any confidentiality issue, or at least significantly reduced).
>> With this sort of opt-in mechanism, the data collected is specific and well-known, thus alleviating the confidentiality issue (for example we would no longer gather the complete list of plugins) and also the size aspect, and consequently making the UDC more consumable by committers since it would allow them to have some sort of eclipse integrated polling system.
