Accumulo 3970
Here's a sketch of what I'm thinking for ACCUMULO-3970. It's by no means
ready to be merged, I just want to send the PR as a starting point for a
discussion.
The idea is to define a new type of iterator, a
VisibilityTransformingIterator, which can be set on a table. The iterator is
only active in scan scope and is applied before the scan authorizations.
Concrete subclasses of the VisibilityTransformingIterator receive individual
key-value pairs that are present in the table and, for each pair, produce zero
or more extra representations of that value. How these extra representations
are produced will probably be driven by how an organization wants to anonymize
or de-identify its data.
