[ZODB-Dev] ZEO client persistent disk cache freshness

[Florent Guillaume]

I'm wondering about the ZEO client persistent disk cache.

When a client stops and is later restarted and reconnects to the 
server, how are issues of freshness dealt with, if at all? Is the data 
that is stored in the cache automatically valid? Does this mean that 
"things" (pickles?) stored on the ZEO server never change for a given 
unique identifier (OID? transaction id?) once they have been created ?

Sometimes ClientStorage logs a "Waiting for cache verification to 
finish" which can take some time, is this related to this?

I hope I'm not too unclear,
Thanks,
Florent
