----------------------------------
Hi, [~busbey]
We sure can try to qualify the performance impact with new numbers :-)
Any suggestions and ideas on how we approach this JIRA is definitely welcomed
as well.
I will also try to outline some thoughts.
> Visibility label security at limited localized level
> ----------------------------------------------------
>
> Key: HBASE-12823
> URL: https://issues.apache.org/jira/browse/HBASE-12823
> Project: HBase
> Issue Type: Improvement
> Components: security
> Affects Versions: 1.0.0, 2.0.0, 0.98.10
> Reporter: Jerry He
> Fix For: 2.0.0
>
>
> 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.
