Subject [jira] [Commented] (ACCUMULO-981) support pluggable encryption codecs for MapFile when recovering write-ahead logs
Date Tue, 12 Mar 2013 19:23:12 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-981?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13600369#comment-13600369
] 

Keith Turner commented on ACCUMULO-981:
---------------------------------------

bq. I'm wondering if it would be easier to make the files used for recovery RFiles with the
Mutation being transformed to a Key

Sorted logs have more than mutations.  They have tablet definitions, start/stop compaction
events, and mutations for multiple tablets.  So its not a 1:1 mapping to RFile.

> As with ACCUMULO-980, we need to support encryption for the recovered write-ahead logs
that are stored as MapFiles in HDFS. Those MapFiles need to support low-latency seeks, so
aligning the encryption with the block compression is a good strategy.
