Hi I am currently using the DIH to connect to and import data from a MS SQL Server, and in general doing full, delta or deletes seems to work perfectly.
The issue is that I spotted some errors being logged in the tomcat logs for SOLR which are : 19-Sep-2011 07:45:25 org.apache.solr.common.SolrException log SEVERE: Exception in entity : product:org.apache.solr.handler.dataimport.DataImportHandlerException: com.microsoft.sqlserver.jdbc.SQLServerException: Transaction (Process ID 125) was deadlocked on lock resources with another process and has been chosen as the deadlock victim.

If it had failed and just rolled back the changes and not updated the dataimport.properties file it would (assuming no more deadlocks) caught all of the missed documents on the next delta import. My connection to MS SQL is using the "responseBuffering=adaptive" setting to reduce memory overhead, So I guess what I am asking is there any way I can cause the DIH to roll back the import if an error occurs and to not update the "dataimport.properties" file.
