Data platforms synchronisation journey at Carrefour by Guillaume Blaquiere

The most large companies, composed of several countries and/or subsidiaries, have several local data platforms. At Carrefour, we have a federated model where each country has its own data platform. While the data platforms are used locally, there is no problem. However, when the headquarters wants to consolidate and aggregate the data from the different data platforms for creating global applications, analytics dashboards or centralized operations, many issues are to solve. Above the data governance and documentation, the data synchronisation is a real challenge. When do you have to get the data from each data platform to join them? Many solutions are possible: using a scheduler, using an orchestrator, using event-driven architecture,... Interactively, we will find and review those solutions, their pros and cons and a demo will present the tool that will be used. #vdc25
