Les différents mode de synchronisation des Data platforms chez Carrefour
The largest companies, composed of multiple countries and/or subsidiaries, have several local Data Platforms. At Carrefour, we have a federated model where each country has its own platform
As long as Data Platforms are used locally, there is no problem. However, when headquarters wants to consolidate and aggregate data from different Data Platforms to create global applications, analytics dashboards or centralized operations, many problems need to be solved. Beyond data governance and documentation, data synchronization is a real challenge.
When should data be retrieved from each Data Platform to cross-reference and aggregate it?
Many solutions are possible: using a scheduler, using an orchestrator, using an event-driven architecture... We will review these solutions, their advantages and disadvantages depending on use cases and requirements.
A demo and interactions with participants are planned for this session
