One recommendation. Be sure to put the documents in a separate family
from the meta data. This will prevent you from having to rewrite the
documents during compactions (since you expect high updates to meta and
not documents).

One other question about performance, we are looking to use the system
to store all
documents that users upload or enter so we will also need to continually
update
document metadata when a user edits it. The edits will be a lot less
frequent than new
documents added. How well does HBase perform with updating cell
values? and how well
does adding rows and updating them scale as the cluster grows?
Individual writes are fast and writes scale roughly linearly as you scale
the cluster; e.g. doubling your nodes doubles the amount of writes you can
take on.
