Subject [jira] [Commented] (HBASE-10077) Per family WAL encryption
Date Wed, 26 Feb 2014 01:53:19 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10077?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13912408#comment-13912408
] 

Andrew Purtell commented on HBASE-10077:
----------------------------------------

One way to handle this is by putting in support for multiple WALs, adding one WAL to the multi-WAL
configuration for encrypted families, and enabling encryption just on that WAL. That could
be a nice clean way to implement this.

> HBASE-7544 introduces WAL encryption to prevent the leakage of protected data to disk
by way of WAL files. However it is currently enabled globally for the regionserver. Encryption
of WAL entries should depend on whether or not an entry in the WAL is to be stored within
an encrypted column family.
