Subject Re: will jackrabbit scale to petabyte repository?

Maybe you shouldn't use just one repository. Unless you have a really
fast computer and storage system (disk / database). Just filling the
repository with that many nodes (on one machine) can take days. The
same for backups, and things like data store garbage collection. You
should consider splitting the data.

With Jackrabbit, you could use multiple repositories (probably on
different machines). Other companies that deal with petabytes of data
(like Google, Yahoo, Facebook) don't just use 'one big database'.

No. I was just curious. Update performance doesn't change a lot for
larger repositories.
