Abstract
A device, system and method for synchronizing databases changes is provided. A change-indication bit-vector indicates a position of a change to a stored data-set and/or a respective key position defined by a data-set representation (DSR) that defines a data-set structure. When the change comprises a data-field deletion, an indication of the change-indication bit-vector is provided to a replication node managing a replica database storing a replica data-set; the replication node updates the replica and a respective DSR to show the deletion at the indicated position. When the change comprises a data-field addition, the indication of the change-indication bit-vector and a record of a key value of a new data field and a data value of the new data field, is provided to the replication database; the replication node updates the replica and the respective DSR to show the addition at the indicated position.
