Subject [jira] [Commented] (SOLR-3262) Remove "threads" from DIH (Trunk only)
Date Thu, 22 Mar 2012 02:03:25 GMT


Chris Male commented on SOLR-3262:


I think this should be a big priority for 4.0, so we don't release the code again.

> SOLR-1352 introduced a multi-threading feature for DataImportHandler.  Historically,
this feature only seemed to work in a limited set of cases and I don't think we can guarantee
users that using "threads" will behave consistently.  Also, the multi-threaded option adds
considerable complexity making code refactoring difficult. 
> I propose removing "threads" from Trunk.  (But keep it in 3.x, applying any bug fixes
for it there.)  This can be a first step in improving the DIH code base.  
> Eventually we can possibly add a carefully though-out "threads" implementation back in.
