3. Name your output and select your Data Sources, then click Next.
Click Properties to review this output's properties. See: Output properties
4. Click the information iconin the fields tree to view information about a field. The following will be displayed:
How many of the events in this data source include this field, expressed as a percentage (e.g. 20.81%).
The percentage distribution of the field values. These distribution values can be exported by clicking Export.
5. Click the information iconnext to a hierarchy element (such as the overall data) to review the following metrics:
The number of fields in the selected hierarchy.
6. Click the plus iconin the fields tree to add a field from the data source to your output. This will be reflected under the Data Source Field in the Schema tab. If required, modify the Output Column Name along with the Column Type.
Note: All numbers are mapped to doubles by default. Change this to BIGINT if you know that your numbers are integers.
Toggle from UI to SQL at any point to view the corresponding SQL code for your selected output.
You can also edit your output directly in SQL. See: Transform with SQL
7. Add any required calculated fields and review them in the Calculated Fields tab. See: Adding calculated fields
