Class DataMetricAttachment

java.lang.Object

dev.frostlake.metastore.model.DataMetricAttachment

public class DataMetricAttachment
extends Object

One DATA METRIC FUNCTION attached to a table, over the columns it measures — or over none, for the table-level metrics (ROW_COUNT, FRESHNESS and their kind).

Frostlake records the attachment and never evaluates the metric: nothing computes a value, and no scheduled run happens. What it does model is the SUSPEND / RESUME state, which is per attachment rather than per table (live-verified).
