Clustering question

[Guido Casper]

After switching "cache-mode" to "cluster" (JDBCStore with 
MySqlRDBMSAdapter) my application experienced a 10-fold performance 
degration. Now I'm considering alternative clustering options :-) like 
having the primary server's "cache-mode" set to "full" and (at least) 
one secondary server's "cache-mode" set to "cluster". All modifications 
go through the primary and the secondary picks up all changes so that 
both servers always deliver uptodate query results. Does that work at all?

Now the secondary server should take the DASL load. It must cover 
queries on properties and full text queries as well.

I think there are 2 possible solutions:
*leveraging the database's (like MySQL's for instance) full text 
indexing capabilities. For this a special version of MySqlRDBMSAdapter 
would have to be written, overwriting storeRevisionContent etc. to put 
certain resourcetypes (text/*) into LONGTEXT columns instead of 
LONGBLOB. And create a corresponding RDBMSTextContainsExpression.

*sharing a Lucene index between instances of Slide
I'm asking for opinions if and how doable either of these is and if I'm 
overlooking something for the first option.

Thanks
Guido
