Yes.  Nice ASCII art. :-)

OK thanks.  To confirm you can have a cluster of Zope instances all using 
relstorage to connect to the same database.  This negates the need for ZEO as 
the database handles the multi-threaded data access.

You can decide for each storage in your application server. At least in
principle you should.

You cannot use both at the same time. Either you use Filestorage/ZEO or 
Relstorage, as in Relstorage the underlying DB takes care of the replication 
features.

Ask this question on either Zope/Plone mailing list.

My understanding about relstorage is that each Zope application client
uses relstorage.
There is no ZEO server in the mix.

Is that correct Shane/others?

[ZODB-Dev] Relstorage and ZEO

2009-03-30 Thread Anthony Gerrard
Hi,

I'm working on a project to migrate a number of sites to a content management 
system.  We finished our evaluation period and chosen Zope / Plone.  I'm new to 
both products and would like some advice about our initial deployment.  The 
impression I get is that using both ZEO and Relstorage are recommended.  My 
question is whether you'd recommend using them together or not.  

The sites get up to half a million requests a day (not page impressions) and 
we're planning on using Apache (mod_cache) and CacheFu for caching.

Anthony
