Subject [jira] [Commented] (HBASE-4132) Extend the WALObserver API to accomodate log archival
Date Mon, 25 Jul 2011 16:26:09 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4132?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13070588#comment-13070588

Andrew Purtell commented on HBASE-4132:

@dhruba Thanks. For example should be preArchiveStart and postArchiveStart, preArchiveCompleted
and postArchiveCompleted. In part it is a naming convention, in part it is a contract: Pre
hooks allow introduction of preprocessing and also important override of default behavior
and associated short-circuiting of base processing or any additional coprocessors. Post hooks
allow introduction of postprocessing and modification of return values.

> The WALObserver interface exposes the log roll events. It would be nice to extend it
to accomodate log archival events as well.
