All your datasources can be viewed in the Datasources tab that can be accessed from the side menu.
You can either setup your datasource using the button or manage its settings using the button.
The details page has the following menus:
View and edit basic information like Name, Description. You can also download your data as a .csv file for "Semi-structured" datasources.
A semi-structured datasource is tabular data but with no rigid schema. In the Setup tab you can configure column-wise settings for the datasource. If this datasource is queried you can apply two types of settings on each column of this datasource:
Allow Filter : Let's you filter data using that column. For example, let's say the column has gender data of a people's group. Then you can use that column as a filter to query data for 'males', 'females' etc.
Display Configuration : This setting lets you configure how you want to show the column data in your results. It has 3 options: Always show in replies, Show when asked by user and Never show in replies.
