dimensions: [list of SQL expressions]

The test will group the results by a given column / columns / valid select sql expression. Under dimensions you can configure the group by expression.

Using this param segments the tested data per dimension, and each dimension is monitored separately.

For example - A column_anomalies test monitoring for null_rate with dimensions configured will monitor the null_rate of values in the column, grouped by dimension, and will fail if in a specific dimension there is an anomaly in null_rate. It is best to configure low-cardinality fields as dimensions.

  • Default: None
  • Relevant tests: dimension_anomalies, column_anomalies, all_columns_anomalies
  • Configuration level: test
