Subject Re: svn commit: r897509 - /couchdb/trunk/etc/couchdb/default.ini.tpl.in
Date Sun, 10 Jan 2010 16:25:54 GMT
Was there a discussion I missed somewhere on making sequential uuid's
the default algorithm? We decided against it when applying the patch
from COUCHDB-465 [1] and I still hesitate to use anything other than
completely random as the default. With the sequential algorithm we're
leaking doc creation times in a non-obvious manner.

I'd rather just see a wiki page on something like "Configuring CouchDB
for improved performance" that went over any config settings to speed
things up with relevant explanations for each. This could also cover
batch inserts with the logic behind the changes.
