Maintaining consistency of data between computing nodes of a distributed computer architecture

A consistency acceleration engine for maintaining consistency of data between data-sets stored in a master database of a master computing node and a replication database of at least one replication computing node of a distributed computer architecture, wherein each time an updated version of a stored data-set is received, the master computing node is configured for updating a corresponding data-set stored in the master database and transmitting replication data relating to the updated data-set version to the at least one replication computing node for replication, each data-set comprising a plurality of data fields arranged in a layout defined according to a corresponding data-set representation (DSR) structure, which is stored together with the corresponding data-set in the master and replication databases, the consistency acceleration engine comprising:

• a master processing module configured to process at the master computing node a stored data-set, the master processing module comprising:
• a data receiving engine configured to receive an updated version of a stored data-set corresponding to a stored data-set in the master database;
• a processing engine configured to process the updated data-set version to generate an updated DSR structure;
• an analyzing engine configured to analyze the updated DSR structure to extract the data fields of the updated data-set version;
• a classification engine configured to classify the extracted data fields into stable data fields, comprising data values that change at a first frequency rate, and volatile data fields, comprising data values that change at a second frequency rate, which is faster than the first frequency rate, the updated DSR structure defining an order of the volatile data fields, and a size of the data values stored in the at least the volatile data fields;
• a bit-vector engine configured to generate a bit-vector storing the data values extracted from the volatile data fields, the data values extracted from the volatile data fields stored in the bit-vector in the order identified by the updated DSR structure;
• a data preparation engine configured to prepare the data to be replicated, the replication data comprising the bit-vector;
• and
• data transmission engine configured to transmit the replication data to the at least one replication computing node;
• and
• a replication module configured to replicate at the at least one replication computing node the replication data, the replication module comprising:
• a replication data receiving engine configured to receive the replication data;
• a replication processing engine configured to process the replication data to extract the data values to be replicated;
• a DSR selection engine configured to select a replication DSR structure corresponding to the replication data;
• and
• a replication engine configured to replicate, based on the selected replication DSR structure, the extracted replication data values in the corresponding replication data-set stored in a replication database.
