Subject Re: "NOT" operator in visibility string

New groups are created on the fly by our application when needed. Under the scenario you describe
we’d have to go through all the data in Accumulo whenever a group is created so that users
in the group can see the existing data.

For example, assume I have two groups of users: group1 and group2. If I want to temporarily
hide something from group1 I would add “& !group1” to the visibility. In my case I’m
not really using the NOT operator for access control. The users in the group have access to
the data; they’ve just chosen to hide it from their view.

just rewrite the data to not include the group1 visibility at all?
