1. A method, comprising:

  • receiving, by a first computing device from a first client of a second computing device remote from the first computing device, at least one request to retrieve at least one data record from a data storage area storing a plurality of data records in sequence order based on sequence identifiers of the plurality of data records, the at least one request comprising a checkpoint value;

    identifying a first data record having a first sequential identifier corresponding to the checkpoint value;

    determining a time difference between a time associated with a most recent stored data record and a current time;

    based on the time difference being greater than a threshold, causing activation of a second client of the second computing device; and

    in response to the at least one request, transmitting, to the second computing device, the first data record and at least one data record having a sequential identifier sequentially after the first sequential identifier.
