What's the status of Tugela-cache? I just downloaded it from http://svn.wikimedia.org/svnroot/mediawiki, but at a quick glance it looks like it hasn't been modified since Nov. 2005?
Ideally, what I need is something like BigTable, i.e. a permanent distributed storage for real-time data serving. It needs to be reasonably fault-tolerant (say a server goes down for a while or a disk goes bad; the system needs to keep working in the meantime, and when the server comes back up, its own contribution to the distributed cache needs to be repopulated transparently). New servers can be added, old ones removed. While we are not a bank (losing a few records would not be catastrophic), it would be bad to lose the content of an entire server. In other words the data must always be present on at least two locations. For each key, my values are arrays of a dozen to a few thousands int64 values. I'd love it to have the possibility to update just one or a few of the elements in the array, rather than the whole array. Any suggestion? Thanks, ~Pierre
