Few days ago one of our customers reported the application being slow.<\/p>\n

We analyzed the situation and found the bottleneck; in his application, one of summary columns calculated count of records based on another summary column that involved complex calculation. And it was not a single case, small fraction of other applications exhibit the same or similar pattern.<\/p>\n

But why you are required to select the column to calculate count of records?<\/p>\n

It’s not a secret, TeamDesk<\/a> uses SQL Server as a database backend. In SQL [Server], the calculating the count over the column takes in account only the records with non-blank<\/strong> values in the selected column. So do we, yet these details were not documented.<\/p>\n

We’ve analyzed all the settings related to Count calculation and found out that 0.5% use "count of formulas" or "count of totals" – it is clearly wrong usage pattern, as you can achieve same result by calculating Count of Id; yet latter is significantly faster.<\/p>\n

You are required to select the value column for Count and, without clear understanding of the behavior users seem to select random one.<\/p>\n

To avoid the misuse we are planning to remove column selection for Count function; this will also streamline setup process a little bit. The Count function will calculate count of related records; if you (still) need count of non-blanks in certain column, you can add "Column is not <blank>" to the filter criteria.<\/p>\n

The update will be issued next week, if you have any questions, please contact support -at- teamdesk -dot- net<\/p>\n","protected":false},"excerpt":{"rendered":"
