Subject [jira] [Commented] (HBASE-7663) [Per-KV security] Visibility labels
Date Wed, 06 Nov 2013 18:19:17 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7663?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13815107#comment-13815107

Andrew Purtell commented on HBASE-7663:
---------------------------------------

bq. Should we have an Interface that is other-than-Mutation that Scan and Get implement (and
Increment i suppose since it retturns a value)? 

I have the same issue over on the cell ACL patch, I need to duplicate these convenience getters
and setters in Get, Mutation, and Scan. It would be good to have a common interface or base
class for Scan and Get, maybe 'Query' (for symmetry with Mutation)? I have fun in places receiving
OperationWithAttributes and then downcasting, that would go away.

> Implement Accumulo-style visibility labels. Consider the following design principles:
> - Coprocessor based implementation
> - Minimal to no changes to core code
> - Use KeyValue tags (HBASE-7448) to carry labels
> - Use OperationWithAttributes# {get,set}Attribute for handling visibility labels in the
API
> - Implement a new filter for evaluating visibility labels as KVs are streamed through.
> This approach would be consistent in deployment and API details with other per-KV security
work, supporting environments where they might be both be employed, even stacked on some tables.
> See the parent issue for more discussion.
