Hi guys-

We have a mission-critical cluster that must be available 24x7 and take a 
very, very heavy load.

- It seems like reindexing is inevitable. Eventually, the database will 
require a reindex for one reason or another (either planned or unplanned.)
- OrientDB seems to halt all DB activity when it's reindexing.
- If a DB needs reindexing, how can we keep our cluster up during that 
time? Has anyone else done this in production?

- Keep in mind that our DB gets 500 writes per second, and so removing 1 
node at a time to reindex may not won't work. It will be out of date by the 
time it finishes reindexing and rejoins the cluster.
- Also, I suspect that a reindexing database will typically affect all 
nodes in the cluster, causing all nodes to go down during reindexing. My 
tests have shown this so far, but I've only done limited testing.

Please let me know the status of this situation right now, and plans for 
the future to deal with reindexing.
