Abstract: A method for managing disbursement signals at a payment system is discussed. The method includes selecting a source of a general disbursement signal indicating a requested transfer of a first portion of funds from a buyer account to a general account at the payment system. The method includes determining an event for transferring a second portion of the funds from the general account to a merchant account. The method includes selecting, based on the event, a source of a merchant signal, the merchant signal indicating a requested transfer of the second portion of the funds from the general account to the merchant account. The method also includes configuring a disbursement module to trigger a transfer of the first portion of the funds in response to receiving the general signal and to trigger a transfer of the second portion of the funds in response to receiving the merchant signal.

Abstract: A method for reconfiguring disbursement signals at a payment system is discussed. The method includes receiving a general disbursement signal for triggering a first fund transfer of a portion of funds from a buyer account to a general account at the payment system, the first fund transfer for purchasing an item via a marketplace. The method includes, in response to receiving the general disbursement signal, performing the first fund transfer. The method includes determining whether a merchant disbursement signal is received from a second source, the merchant disbursement signal for triggering a second fund transfer of a portion of the funds from the general account to the merchant account. The method also includes determining, based on whether the merchant disbursement signal is received from the second source, whether to reconfigure a disbursement module to receive a different merchant disbursement signal for triggering the second fund transfer.

Abstract: A method for managing transaction queues is discussed. The method includes receiving, from a marketplace, a first communication indicating a cart, the cart comprising items for purchase, the items originating from one or more sellers. The method includes performing a first risk analysis on the cart to determine whether to accept the cart for processing into a queue, the first risk analysis being a cart-level analysis. The method also includes, in response to determining to accept the cart, adding requested transactions for the items to the queue. The method includes performing a de-queueing operation for a selected requested transaction from the queue for processing. The method also includes performing a second risk analysis on the selected requested transaction as part of determining whether to process a payment for the selected requested transaction, the second risk analysis being a transaction-level analysis.

Abstract: A method for managing de-queuing of transaction queues is discussed. The method includes determining a queue capacity of a queue, where the queue includes a plurality of requested transactions. The requested transactions indicate items for purchase from one or more sellers, and the queue capacity indicates a capacity of the queue to store requested transactions. The method includes determining a transaction capacity of a processing module, where the transaction capacity indicates capacity of the processing module to process a number of requested transactions. The method also includes determining, based on the queue capacity and the transaction capacity, whether to limit a de-queue rate at which the requested transactions are de-queued from the queue by the processing module. In response to determining to limit the de-queue rate, the method adjusts operation of the processing module.
