You can provide an upper limit on the number of rows in a visual request.
By default, the system fetches 5,000 rows at a time.
To change the default, navigate to the Data menu, and change the value under the heading Maximum number of rows to fetch.
Note that for table visuals only, the value on the Limit shelf in the Visual Designer overrides this setting.
You can also change this setting on the Data tab of a filter widget. See Specifying Maximum Numbers of Rows to Fetch.
