Resolution: Won't Fix
DIH has moved to https://github.com/SearchScale/dataimporthandler
> Option to have updateHandler and DIH skip updateLog
> ---------------------------------------------------
>
> Key: SOLR-3954
> URL: https://issues.apache.org/jira/browse/SOLR-3954
> Project: Solr
> Issue Type: Improvement
> Components: update
> Affects Versions: 4.0
> Reporter: Shawn Heisey
> Priority: Major
> Fix For: 6.0, 4.9
>
>
> The updateLog feature makes updates take longer, likely because of the I/O
> time required to write the additional information to disk. It may take as
> much as three times as long for the indexing portion of the process. I'm not
> sure whether it affects the time to commit, but I would imagine that the
> difference there is small or zero. When doing incremental updates/deletes on
> an existing index, the time lag is probably very small and unimportant.
> When doing a full reindex (which may happen via DIH), especially if this is
> done in a build core that is then swapped with a live core, this performance
> hit is unacceptable. It seems to make the import take about three times as
> long.
> An option to have an update skip the updateLog would be very useful for these
> situations. It should have a method in SolrJ and be exposed in DIH as well.
