Today Faidon replied on IRC: >> ...I'm pretty much against moving forward with this unless the simplify RFC<https://www.mediawiki.org/wiki/Requests_for_comment/Simplify_thumbnail_cache>gets implemented...
That RFC was created in 2013-10-07 (5+ months ago), and has not been finalized nor have I found any resources allocated to this project, so it might be a while. Now the question seems to be - would this impact our infrastructure in a significant way without simplify RFC? My calculations<https://www.mediawiki.org/wiki/Talk:Requests_for_comment/Reducing_image_quality_for_mobile#Impact_on_infrastructure> based on Faidon's data suggest that maximum disk usage growth would be 250-500GB extra data size (2.5% growth of the current 20TB), which also equate to 15% increase in the number of files. Hence: 1) are these numbers logical? 2) assuming (1), does 2.5% size growth and 15% number of files growth seem too taxing on our infrastructure to require waiting for simplify RFC technology? >> ... this is one of the things that as we discussed, we need to plan ahead in quarterlies etc.; you can't just drop that on us and start experimenting, sorry This project is following the regular steps - I published it on RFC and posted a proposed code patch. There is no experimentation, only discussion. Even implementing core feature does not increase storage requirement until we have a go ahead from Ops and Mobile and update javascript to use new functionality. Please elaborate what should be the appropriate steps that I might have missed.
