Description
Currently, if visibility label security is enabled for a HBase instance, after VisibilityController is configured, the cell level visibility label filtering will kick in across the HBase instance.
Cell level visibility label filtering has non-negligible performance impact.
On the other hand, in many use cases, only a small portion of the overall data needs visibility label protection.
If we can support visibility label security at a limited and localized level, we will broaden the use cases and the adoption of this feature.
We should be able to support visibility label security at per table or per column family level. This is quite common in many other HBase features.
Cell level visibility label filtering will only be enabled and kick in for the tables or column families that the user designates.
