We currently use memcached to share cached objects across wikis, most importantly, entity objects (like data items). Ori suggested we should look into alternatives. This is what he wrote: [21:15] <ori> I was wondering if you think the way you use memcached is optimal (this sounds like a loaded question but I mean it sincerely). And if not, I was going to propose that you identify an optimal distributed object store, and I was also going to offer to help push for procurement and deployment of such a service on the WMF cluster. [21:17] <ori> memcached is a bit of a black box. it is very difficult to get comprehensible metrics about how much space and bandwidth you're utilizing, especially when your data is mixed up with everything else that goes into memcached [21:18] <ori> and the fact that you're serializing objects using php serialize() rather than simple values makes it even harder, because it means that you can only really poke around from php with wikidata code available Just food for thought, for now... any suggestions for a shared object store? In any case, thanks for looking into this, Ori! -- Daniel Kinzler Senior Software Developer Wikimedia Deutschland Gesellschaft zur Förderung Freien Wissens e.V.
