I would start using Solr Cloud now (keep experimenting), so that you
will have a chance to work on setting it up, creating and managing
collection, using it from your clients etc. Solr Cloud is very different
from simple standalone 3.5 Solr, so you have a lot to learn about how it
works before you are ready to use it in production. You can start that
now, but maybe you dont want to go into production with Solr Cloud
before 4.1. It depends on your "requirements on quality" if 4.0 is ready
for production, but I believe the same will be true for 4.1. There will
be a lot of fixes in 4.1, but Im sure there will still be lots of
unfixed "issues". Best way (as always) is to test if your system works
as it is supposed to when it is based on Solr 4.0.
I wouldnt start using Solr Cloud replication if you are running under
high load - it has (or had a month or two ago) a lot of issues, and IMHO
it is not ready for production usage - unless a lot happend within the
last months, and I couldnt imagine. We have just relased the first
production version of our product based on 4.0 plus a bunch of "our own"
fixed and improvements. This version of our product does not support
replication, simply because we have seen to many issues with Solr Cloud
replication - especially under high load. Replica is a goal for version
1.x of our product and we are about to start up a phase where we will
have a lot of focus on stabilizing Solr Cloud replication - hopefully we
will succeed in collaboration with the rest of the Solr community, and
hopefully Solr Cloud replication will be production ready within the
next half year.

Hi,
If you are not in a rush, I'd wait for Solr 4.1. Not that Solr 4.0 is not
usable, but Solr 4.1 will have a ton of fixes.

Hi,
We have been using solr 3.5 in our production for sometime now and facing
the problems faced by a large solr index. We wanted to migrate to Solr
Cloud and have started some experimentation. But in the mean time also
following the user forum and seem to be noticing a lot of bugs which were
raised post the release and will be fixed in 4.1.
Should we wait for 4.1 release for production or we can go ahead with the
current release?
