A computer receives a first user input linking a first output of a first task to a second task. The first task is scheduled for execution at a specific time. The computer receives a second user input selecting a third task from a list of additional tasks that are downstream from the second task. In response to the second user input, the computer links the third task to a second output of the second task. At the specific time, the computer automatically executes the first task and updates the first output of the first task. After updating the first output of the first task, the computer automatically executes the second task that is linked to the first output of the first task, including updating the second output of the second task. After updating the second output of the second task, the computer automatically executes the third task.

Linking outputs for automatic execution of tasks

A user interface includes a data flow pane and a profile pane. The data flow pane displays a flow diagram that identifies a data source. For each of multiple queries against the data source, the process issues the query against the data source asynchronously with a block size. Upon retrieval of the initial set of rows, the process repeats the query asynchronously until all of the rows have been retrieved. Periodically the process determines a high water mark for rows from the data source that have been retrieved for all of the queries. When the water mark changes, the process updates the profile pane to display statistical distributions of data values for multiple data fields in the data source. Each distribution element in each statistical distribution counts the rows below the water mark that have a single specific data value or range of data values.

Each bar in each data value histogram counts the rows below the water mark that have a single specific data value or range of data values.
