Piotr Kliczewski has submitted this change and it was merged. Change subject: db: memory_and_disk_images_storage_domain_view - EXISTS instead of JOIN ...................................................................... db: memory_and_disk_images_storage_domain_view - EXISTS instead of JOIN Change Ifbedd49da added indexes and changed the memory_and_disk_images_storage_domain_view view to use JOIN instead of EXISTS to determine if the disk is a memory disk/ovf store. On certain datasets and under load that causes postgres to execute the query slower. As we yet to find a case in which using EXISTS for those tables causes to a problem, this patch restores the use of it in the view.
