Subject [jira] [Commented] (COUCHDB-994) Crash after compacting large views
Date Tue, 14 Jun 2011 15:15:49 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-994?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13049231#comment-13049231

Adam Kocoloski commented on COUCHDB-994:
----------------------------------------

The general idea looks right, but it doesn't address the core problem in this ticket, namely
that a well-timed crash can reset the view index.  I'll take a closer look at the particulars
of the patch later today.

> The database has over 9 million records. Several of the views are relatively dense in
that they emit a key for most documents. The views are successfully created initially but
with relatively large sizes from 20 to 95G. When attempting to compact them, the server will
crash upon completion of the compaction.
> This does not occur with the released 1.0.1 version but does with the 1.0.x svn version.
I'll attach example logs. Unfortunately they are level error and may not have enough information.
