Hi Steve,
Could you explain the details of what "clustering" really means in this context?

Yep, that's us. No secret, just didn't want to make my question an
billboard :-). Just needed a bit of info from the people who know
best.

Sure,
I'm fairly new to Lucene but what I was trying to do was make it so
that an index could be shared among multiple nodes. If an index is
updated in any way it would be updated across the cluster coherently.
In my first version I was really only taking advantage of the fact
that we detect fine
it?
Solr has a different approach. There, only the master index is modified, while
slave servers copy the master index periodically.

I'm not really clear on what the "small thing" is that you are asking

an alternative? If you've got a patch that
Fair question.
All I did/need was take SegmentInfos and instead of subclassing Vector
I made it contain a Vector. Went from subclassing to aggregation. As

While automatically clustering java objects sure sounds cool, I have
to wonder what the performance ends up being. Every small change to
the clustered objects is broadcast to all the nodes, correct?
Have you done any performance comparisons to see if this is a
practical approach for Lucene?

Good question. May or may not be performant enough. Only time (and
testing) will tell. My guess is that it will depend heavily on the
rate in which the data changes (or read write ratio).
Believe me, I'm not proposing that everyone go out and cluster lucene
with terracotta dso. I'm really just pl

I'm don't know list servers rules but I figured I would just include

Would this change break anything or bother anyone?

So I switched to clustering the RAMDirectory instead of the
IndexWriter and it worked in my experiments. What I did was create a
new IndexWriter on Document Adds and a new IndexSearcher on document
queries.
What I want to know is. How non-standard is this approach?
