  • Patent number: 10721321
    Abstract: In some embodiments, a method comprises: receiving update data from a data source, the update data being part of a data feed from the data source; in response to receiving the update data from the data source, storing the update data in a data buffer; transmitting the update data from the data buffer to a data transformer, the data transformer being configured to transform the update data and to transmit the transformed update data to an online service, the update data being continued to be stored in the data buffer subsequent to the transmitting of the update data to the data transformer; receiving a request for retransmission of the update data from the data buffer to the data transformer, and in response to the request for retransmission, retransmitting the update data from the data buffer to the data transformer.
