An account can stipulate thresholds for sending and receiving hbars. If and when a transaction surpasses a threshold, a record for that transaction is automatically created and persisted for 24 hours (rather than the default 3 minutes). The account that stipulated the thresholds will pay for the creation and storage of that record. Any clients that subsequently query for that record (within the 24 hours) will pay for that query.
