Subject [jira] [Commented] (ACCUMULO-980) support pluggable codecs for RFile
Date Sat, 26 Jan 2013 17:33:12 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-980?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13563561#comment-13563561

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

RFile is also used to dump the in-memory map to support isolation of long scans. See org.apache.accumulo.server.tabletserver.InMemoryMap.delete(long).
We'll need to make sure the same RFile encryption configuration applies there.

> 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.
