Member Data Documentation

int64 net_instaweb::SharedMemCacheData::SectorStats::num_put

FS operation stats — updated by SharedMemCache. We do it this way rather than using the normal Statistics interface to avoid having to worry about extra synchronization inside critical sections — since we already hold sector locks when doing this stuff, it's easy to update per-sector data.

Todo:

TODO(morlovich): Consider periodically pushing these to normal Statistics.
