Ferret talk - Jan 2006 - Question on scalability

Hi all,

I''ve had a lot of fun over the last couple of days integrating Ferret
with
my Rails app.   Many thanks to Dave Balmain for writing this.   Everything
seems to work well and my site now has full search capabilities.   But
I''m
wondering how I can scale my site now?

What would be the recommended approach in terms of sharing indexes across
multiple servers?    Is the solution to use a shared filesystem?    Is it ok
for multiple applications to update the indexes concurrently?

Thanks,

Joe

I''d try using a DRb server for the index. It''s very easy to
implement
and should avoid locking problems.

In my experience, no. I often had problems with stale lockfiles and 
other weird behaviour, and I found it much more reliable to use only one 
writing process.
