entity key collisions merge two customers into one feature row error

Switch the entity key to the stable unique customer id and stop keying on a normalised email or name, then rebuild the affected rows, because two different customers collapse into one feature row when the join key value is identical for both. Use when you see this exact failure: entity key collisions merge two custome…

point in time join leaks future features only for entities with multiple events failure

Break timestamp ties with the created or ingestion timestamp so the join picks the latest feature row at or before the label event and never a later one, adding a strict event timestamp less-than-or-equal filter per entity, because entities with multiple close events are exactly where a loose join reaches into the fut…

Chronon upload failed error "conf file validation failed: join has no group_bys"

Add at least one group_by to the join conf and run the conf validation again before uploading, because a join with no group_bys has no features to compute and the validator rejects it at upload rather than letting a featureless join deploy. Use when you see this exact failure: Chronon upload failed error "conf file va…
