When bulk loading large volumes of data into MDM, authorized users can configure two parameters
bulkload.concurrent.wait.millisecondsin the file <$INSTALLDIR>/conf/mdm.conf to avoid transaction and deadlock issues since too many threads on the server side are trying to obtain database connections.
Authorized users can edit the file <$INSTALLDIR>/conf/mdm.conf to define the maximum number of data records to be exported or imported in Talend MDM Web User Interface. By default, an authorized user can import or export a maximum of 1000 records.
Authorized users can change the number of migration threads specified by the parameter
db.migration.threadsin the file <$INSTALLDIR>/tools/dbmigration/dbmigration.properties to reduce the time for migration.
