DurationHow long the comparison took.
OriginWhether the run was triggered from the Web UI or CLI.
Created AtTimestamp of the run.
Comparison TypeDeep, Shallow, or Schema.
Semantic SimilarityWhether semantic similarity detection was enabled.
Summary metrics
MetricDescription
Rows ComparisonSource and target row counts side by side.
Schema ComparisonNumber of columns analyzed.
Primary KeysCount of exclusive keys in source and target.
Values ComparisonNumber of columns with differing values.

​
Schema tab

The Schema tab shows the structural alignment between the two datasets.
ColumnDescription
Source / Target NameDataset and column names.
TypeData type of each column.
Schema StatusWhether the column schema is identical or has differences.
Values StatusPercentage of rows with value differences in that column.
Exclusive ValuesCount of values that exist in only one dataset.
Filters: Filter by schema status or values status, or search by column name.

​
Primary Keys tab

The Primary Keys tab breaks down key-level differences:
  • Duplicate PKs in Source — Primary key values that appear more than once in the source.
  • Duplicate PKs in Target — Primary key values that appear more than once in the target.
  • Rows exclusive to Source — Records that exist only in the source dataset.
  • Rows exclusive to Target — Records that exist only in the target dataset.

​
Values tab

The Values tab highlights column-level value differences between the two datasets.
  • Each row shows a column with the percentage and count of differing values.
  • Toggle Semantic Similarity to surface near-matches alongside exact differences.
  • The diff table uses color coding: red for significant differences, yellow for partial similarity, and no color for identical values.
  • Hover over a cell to see the similarity score.
  • Use Columns toggle to show only changed columns and their primary keys.
