org.apache.marmotta.kiwi.loader.pgsql.KiWiPostgresHandler
A fast-lane RDF import handler for PostgreSQL backends. This importer takes advantage of the PostgreSQL COPY command that allows direct injection into the database. It works by creating an intermediate CSV buffer that is flushed into the databases in batches (using a configurable batch size). @author Sebastian Schaffert (sschaffert@apache.org)

            loaderConfiguration.setDropIndexes(configuration.getBoolean("backend.kiwi.drop-indexes", false));


            if(kiwi.getDialect() instanceof PostgreSQLDialect) {
                log.info("- using PostgreSQL bulk loader ... ");
                loaderConfiguration.setCommitBatchSize(100000);
                handler = new KiWiPostgresHandler(store,loaderConfiguration);
            } else if(kiwi.getDialect() instanceof MySQLDialect) {
