Data synchronization, incremental/bulk updates.. We all know these problematic words but who knows that the restless human mind has already systematized this field?
Lady and gentlemen, let me introduce Change data capture design pattern.
Wikipedia says:
Change data capture (CDC) is a set of software design patterns used to determine (and track) the data that has changed so that action can be taken using the changed data. Also, Change data capture (CDC) is an approach to data integration that is based on the identification, capture and delivery of the changes made to enterprise data sources.
You won't find any concrete class diagram in CDC pattern. But definitely will get some ideas and best-practices of data sync implementation.
