A device, system and method for distributing and locally persisting provider objects is provided. A first device provides, in a provider object stream, first indications of first provider objects, generated and locally persisted in association with a first region, to a second device associated with a second region. The first device receives, in the stream, from the second device, second indications of second provider objects generated locally persisted in association with the second region, the second indications including respective identifiers identifying the second region. The first device: discards given second provider objects, indicated by the second indications, which do not meet a local persistence condition; and locally persists other second provider objects, as indicated by the second indications, which meet the local persistence condition, the other second provider objects locally persisted in association with the first region.

Device, system and method for distributing and locally persisting provider objects

The present invention relates to a method and a system for maintaining consistency of data between data-sets stored in a master database of a master computing node and corresponding data-sets stored in a replication database of at least one replication computing node. 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. The replication data comprising a bit-vector storing data values extracted from data fields of the data-set classified as volatile data fields. The data values stored in the bit-vector representing the changes in the data-set to be replicated in the at least one replication node.
