As an aside, we find management of ZEO clients much easier if each ZEO
client of a particular system shares the same products and external
methods via an NFS share. That way we can untar one product and
push it
out to all of the clients simultaneously.
I'd be a little afraid of creating a

This would require how much RAM for the index? :-)
It can hold 16 billion billion pointers, with each pointer being 48
bits, thats 96 exabytes (100 million terabytes). Just for the index.

ZODB size
What is the maximum size of this file and/or maximum object ID?
= just how many objects can the zodb hold? millions? tens of
millions..?? billions...??? I have a feeling we'll run out of ram
long before actually hitting the limit but it'd be nice to know the
theoretical top limit.

No one has come against a limit yet as far as I know. Hitting RAM
limits depends on the settings you apply to the Zope/ZEO instance(s)
that serve(s) the content and how much RAM you put in, you can
control ZODB

Well, the question was actually What is the maximum size of this
file and/or maximum object ID? = just how many objects can the zodb
hold?. There is only a theoretical limit that has to do with the
largest index key for the ZODB index I believe, and that is some
ludicrously

If you're using FileStorage, a technical detail in the implementation
of the FileStorage index limits the maximum file offset that can be
used to 2**48-1, or about 281 terabytes. Object IDs are effectively
64-bit integers (masquerading as 8-byte strings).
