Subject Skipping duplicates in DataImportHandler based on uniqueKey
Date Sun, 02 May 2010 15:47:50 GMT


Is there a way to get the DataImportHandler to skip already-seen records
rather than reindexing them?

The UpdateHandler has an <add overwrite="false" ... > capability which (as I
understand it) means that a document whose uniqueKey matches one already in
the index will be skipped instead of overwritten.

Can the DIH be made to behave this way?

If not, would it be an easy patch? This is using the XPathEntityProcessor by
the way.
