Hi Yarek, Others may add to this, but the big issues I'm aware of are:
BDB + fast + can be shared among multiple processes on a single machine - commercial use requires license Postmodern - 5x slower than BDB (last I checked) ++ can be shared among multiple machines + open source Neither system allows you to easily bypass the elephant representational framework. I'll let others comment on this vis-a-vis postmodern. You can use both system's tools for archive, recover, duplication, etc. Ian On Jan 2, 2009, at 2:17 PM, Yarek Kowalik wrote: > Could someone point me to any discussions WRT to choice of back- > end?
