Shashidhar,

It's not necessary to limit to 1 forest to avoid exceeding your
hardware. Forests are just partitions of your database, much like stands
are partitions of a forest. For a given number of documents in your
database, your disk footprint will be comparable, whether you have 1
forest or 6.

If you add additional forests to your database, the rebalancer will
spread documents across all of the forests. This will, however, consume
a fair bit of I/O since the rebalancer is transactional and will create
new stands in the new forests, which will then merge into large stands
in those forests. As documents are rebalanced out of your current
forest, merges will also occur there to reclaim disk space by removing
the deleted documents.

An additional benefit of adding more forests is that you will be able to
ingest new documents at a higher rate due to increased parallelism
across the forests.

Wayne.
