/**
 * Inspects the row processed tables primary keys. If all primary keys are
 * in the source columns of the AnalysisJob, they will be added to the
 * physically queried columns.
 *
 * Adding the primary keys to the query is a trade-off: It helps a lot in
 * making eg. annotated rows referenceable to the source table, but it may
 * also potentially make the job heavier to execute since a lot of (unique)
 * values will be retrieved.
