+  Estimated throughput: at most one additional API call for each Job Pod reaching
+  Ready condition per second. The reason is that the update of the `.status.ready`
+  field may trigger another reconciliation of the Job. In order to constrain the
+  number of reconciliations within a second, the Job controller batches and
+  deduplicates reconciliation requests within a second. In other words, if there
+  is another reconciliation request planned within a second, the one triggered
+  by `.status.ready` update is skipped.
