Computed Fields Details

Computed Field Details provides a quick overview of the metrics generated from a computed field. The Totals section summarizes the results produced by this computed field and displays a report that reflects only the data output of this specific computed field.

Totals

1 Quality Score: This provides a comprehensive assessment of the overall health of the data, factoring in multiple checks for accuracy, consistency, and completeness. A higher score, closer to 100, indicates optimal data quality with minimal issues or errors detected. A lower score may highlight areas that require attention and improvement.

2 Sampling: This shows the percentage of data that was evaluated during profiling. A sampling rate of 100% indicates that the entire dataset was analyzed, ensuring a complete and accurate representation of the data’s quality across all records, rather than just a partial sample.

3 Completeness: This metric measures how fully the data is populated without missing or null values. A higher completeness percentage means that most fields contain the necessary information, while a lower percentage indicates data gaps that could negatively impact downstream processes or analysis.

4 Active Checks: This refers to the number of ongoing quality checks being applied to the dataset. These checks monitor aspects such as format consistency, uniqueness, and logical correctness. Active checks help maintain data integrity and provide real-time alerts about potential issues that may arise.

5 Active Anomalies: This tracks the number of anomalies or irregularities detected in the data. These could include outliers, duplicates, or inconsistencies that deviate from expected patterns. A count of zero indicates no anomalies, while a higher count suggests that further investigation is needed to resolve potential data quality issues.

Profile

This provides detailed insights into the characteristics of the field, including its type, distinct values, and length. You can use this information to evaluate the data's uniqueness, length consistency, and complexity.

No	Profile	Description
1	Declared Type	Indicates whether the type is declared by the source or inferred.
2	Distinct Values	Count of distinct values observed in the dataset.
3	Min Length	Shortest length of the observed string values or lowest value for numerics.
4	Max Length	Greatest length of the observed string values or highest value for numerics.
5	Mean	Mathematical average of the observed numeric values.
6	Median	The median of the observed numeric values.
7	Standard Deviation	Measure of the amount of variation in observed numeric values.
8	Kurtosis	Measure of the ‘tailedness’ of the distribution of observed numeric values.
9	Skewness	Measure of the asymmetry of the distribution of observed numeric values.
10	Q1	The first quartile; the central point between the minimum and the median.
11	Q3	The third quartile; the central point between the median and the maximum.
12	Sum	Total sum of all observed numeric values.

You can hover over the (i) button to view the native field properties, which provide detailed information such as the field's type (numeric), size, decimal digits, and whether it allows null values.

Last Profile

The Last Profile timestamp helps users understand how up to date the field is. When you hover over the time indicator shown on the right side of the Last Profile label (e.g., "1 week ago"), a tooltip displays the complete date and time the field was last profiled.

This visibility ensures better context for interpreting profile metrics like mean, completeness, and anomalies.

Delete a Computed Field

Deleting a computed field permanently removes both the transformation definition and its output field. This is the only way to remove a computed field — computed fields cannot be excluded.

From the Field Listing

1. Navigate to the container's field listing.
2. Locate the computed field you want to delete.
3. Click the vertical ellipsis menu (⋮) on the field row.
4. Click the Delete option from the menu.
5. Confirm the deletion in the dialog.

From the Field View

1. Navigate to the computed field's detail page by clicking on the field name in the container's field listing.
2. Click the Delete button in the top-right corner of the field page.
3. Confirm the deletion in the dialog.

What Happens When a Computed Field is Deleted

• The transformation definition is permanently removed
• The output field is permanently removed
• Any quality checks associated with the output field are deleted
• Source fields are not affected — they retain their status and configuration

Warning

This action is irreversible. Unlike excluding a source field (which preserves the computed field definition for later restoration), deleting a computed field permanently removes the definition and all associated data.

Note

This is different from what happens when a source field is excluded. When a source field is excluded, the computed field output is also excluded but the definition is preserved, allowing restoration later. When you delete a computed field directly, the definition is permanently lost. For more details, see Computed Fields and Exclusion.
