Usage of a transactional clock in a distributed financial operations support system to speed up the data reconciliation process

The object of the study is the data reconciliation process in distributed systems using a non-relational database. The aim of the work is to improve the efficiency of the data reconciliation process in distributed systems supporting financial operations. The article provides results of several experiments on systems using different data reconciliation mechanisms. Based on the analysis of the experiment results, to achieve the goal, it is proposed to use the transactional clock and the embedded concept of critical data, which leads to the optimization and significant enhancement of the overall efficiency of financial operations support systems by several times.
