Hi, Can you elaborate more on "can be configured to work as a pool, by recycling database instances"? Perhaps an example of this pooled mode?
And on how it should be treated for embedded mode when creating missing databases (if the database doesn't exist, it’s created automatically (but in “remote” mode)). For my case there is not "remote" mode... I think :). Regards, -Stefán On Friday, January 31, 2014 11:17:42 AM UTC, Lvc@ wrote: > > Hi all, > this is the first version of the new Graph Factory.
