Min Partition Size Anomaly Reporting

How the Min Partition Size check reports violations: the Shape Anomaly it produces, what the numbers mean, and how a partition-level anomaly differs from a row-level one.

Anomaly Messages

Min Partition Size always reports a Shape Anomaly, one per failing partition. There is no Record Anomaly: the rule evaluates a count, not individual rows, so there is no offending row to point at.

Shape Anomaly

<container> holds <observed> records, fewer than the required <limit>

Reading the message:

  • <container> is the table or file the check runs on.
  • <observed> is the number of records actually loaded from the failing partition.
  • <limit> is the Minimum partition size configured on the check.

The partition that failed is named on the anomaly itself, in its Partition attribute, rather than inside the message.

Because the anomaly is raised against the partition rather than against a set of rows, the Source Records view does not list violating records: there are none to list. What the anomaly gives you is the partition and the two counts.

Custom Anomaly Description does not apply to this rule. The option replaces the message on Record Anomalies, and Min Partition Size emits a Shape Anomaly only.
