I begin to start to study tableau these days and meet a problem. When I run a table left join two tables in my desktop, it runs well. However, when I add it to a plan in the server, it runs about 2500 seconds and fails at the end. The tips of the server is that "com.tableausoftware.nativeapi.dll.DataSourceException: Unable to materialize temporary table". If anybody had met it also and could resolve it, please help me. Thanks!
