How increase the threshold for List View in App for SharePoint 2013 if count is more than the Threshold value.

Generally it is not recommended to increase these limits, they are there for a reason (SQL server can get database locked for large operations). But still the limit can be raised a bit for normal use. We're running some web apps with 10,000 as the cap. For temporary situation I've tested up to 600,000 but that should be just for very brief and specific needs.
