Subject Re: bi-directional replication on solr 1.4?
Date Thu, 13 May 2010 21:14:25 GMT
It looks like doesn't allow for the possibility of the
slave having a later index version than the master. It only checks
whether the versions are equal.

It's easy enough to add that check and prevent the index fetch when
the slave has a later version (in fact I'm running it in a sandbox
right now). But I wonder what other problems it might create in a
production environment (or what problems I am overlooking). Does
anyone have any thoughts on this?
