How many unique values appear in this field.
The total number of values ingested for this field.
The first time this field included a value, for example, a year ago.
The last time this field included a value, for example, 2 minutes ago.
The percentage distribution of the field values. These distribution values can be exported by clicking Export.
A time-series graph of the total number of events that include the selected field.
The most recent data values for the selected field and columns. You can change the columns that appear by clicking Choose Columns.
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.
The number of keys in the selected hierarchy.
The number of arrays in the selected hierarchy.
A stacked bar chart (by data type) of the number of fields versus the density/distinct values or a stacked bar chart of the number of fields by data type.
A list of the fields in the hierarchy element, including Type, Density, Top Values, Key, Distinct Values, Array, First Seen, and Last Seen.
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.
7. Add any required calculated fields and review them in the Calculated Fields tab. See: Adding calculated fields
8. Add any required lookups and review them under the Calculated Fields tab.
9. Through the Filters tab, add a filter like
WHERE in SQL to the data source.
See: Adding filters
10. Click Make Aggregated to turn the output into an aggregated output. Read the warning before clicking OK and then add the required aggregation. This aggregation field will then be added to the Schema tab. See: Aggregation functions
12. Partition the data by clicking More > Manage Partitions and then selecting the following:
Key: Partitions the data table using one or more fields (or calculated fields)
Partitioning Time: Partitions the data table using a specific time field
13. To keep only the latest event per upsert key, click More > Manage Upserts then select the following:
Keys: A unique key identifying a row in the table
Deletions: The delete key (events with the value true in their deletion key field will be deleted)
14. Click Run and fill out the following fields:
S3 Storage: The storage for the data of the table; the access key of this storage must belong to the same AWS account as the access key of the selected connection
Connection: How to create a new connection
See: Running an output
15. Click Next and complete the following:
Select the compute cluster to run the calculation on. Alternatively, click the drop-down and create a new compute cluster.
The range of data to process. This can start from the data source beginning, now, or a custom date and time. This can never end, end now or end at a custom date and time.
16. Finally, click Deploy to run the output. It will show as Running in the output panel and is now live in production and consumes compute resources.
