Hi, I have MonetDB JUL2015-SP2, with table of 100M rows and 20 coluns, 4 of number type, others string type. A simple "select count(*) from table", run on 90 minutes. Hardware and SO is: Debian 8, 4 cores, 11G RAM and 20G free on disc. While monet run the query, command top, show 42G of virtual memory. Its normal ?, any idea ? thanks. -- Luciano Sasso Vieira Data Scientist & Solutions Architect luciano@gsgroup.com.br http://www.gsgroup.com.br | tel: 17 3353-0833 | cel: 17 99706-9335 www.gsgroup.com.br http://www.gsgroup.com.br --- Este email foi escaneado pelo Avast antivírus. https://www.avast.com/antivirus
