As my Gallery now hosts nearly 300.000 pictures I think that might cause problems when upgrading. So can anyone tell me if its save to delete the caches before upgrading. (There are old files from 2004, and sure over a million files all together). Is G2.3 coming with an improved cache managment ? Or can I manually empty those cache dirs safely from time to time? |

In theory you can delete anything in g2data/cache at any time. However ... /cache/derivative holds the thumbnails, resizes etc, and some servers will overload if they're forced to rebuild them en-masse on-the-fly (thread and memory limitations on the server etc) and once a lot of derivatives fail to rebuild and are marked as 'broken' it can be hard to recover them. So I would leave that folder intact.
A million cache files for 300k images is to be expected: each resize, each thumbnail and each watermarked-version of each image generates two or more files.
The cache management in 2.3 is as far as I know unchanged.
I don't think that there's any benefit in deleting any of the cache contents specifically before upgrading. I shall wait to hear if anyone disagrees.
