do you think that the option responseBuffer="adaptive"
should solve my problem ? >From DIH FAQ ...: I'm using DataImportHandler with MS SQL Server database with sqljdbc driver. DataImportHandler is going out of memory. I tried adjustng the batchSize values but they don't seem to make any difference. How do I fix this? There's a connection property called responseBuffering in the sqljdbc driver whose default value is "full" which causes the entire result set to be fetched. See http://msdn.microsoft.com/en-us/library/ms378988.aspx for more details. You can set this property to "adaptive" to keep the driver from getting everything into memory. Connection properties like this can be set as an attribute (responseBuffering="adaptive") in the dataSource configuration OR directly in the jdbc url specified in DataImportHandler's dataSource configuration. -- View this message in context: http://lucene.472066.n3.nabble.com/DIH-Full-Import-DB-and-Performance-tp861068p861134.html Sent from the Solr - User mailing list archive at Nabble.com.
