Subject [jira] [Commented] (ACCUMULO-980) support pluggable codecs for RFile
Date Fri, 01 Feb 2013 21:48:12 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-980?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13569129#comment-13569129

Adam Fuchs commented on ACCUMULO-980:
-------------------------------------

If the plugin is given some information as to which key to use and to lookup keys or query
a service, then the rekeying should be implementable within the plugin. As long as we tie
the session key used to encrypt the RFile to some other key and record that linkage in the
file, then the plugin should be able to lookup old keys or use a service to decrypt old keys
after the key is cycled. I believe this is in the current design, as part of the crypto info
block.

> As part of the encryption at rest story, RFile should support pluggable modules where
it currently has hardcoded options for compression codecs. This is a natural place to add
encryption capabilities, as the cost of encryption would likely not be significantly different
from the cost of compression, and the block-level integration should maintain the same seek
and scan performance. Given the many implementation options for both encryption and compression,
it makes sense to have a plugin structure here.
