Abstract: Gaia is an astronomy mission of ESA, based on a satellite launched on December 19th, 2013. Its main goal is to map more than 1 billion stars and sky objects. The scientific data processing is delegated to the Data Processing and Analysis Consortium (DPAC), and relies on 6 Data Processing Centres (DPC) spread all around Europe. The CNES Data Processing Center (DPCC) is one of the main DPCs in charge of operating several scientific tasks. After more than 3 years of operations and continuous development, this paper points out the main strategies adopted face to the rise of complexity in terms of data handling, scientific functionalities in constant evolution and operational timeline constrained by the rest of the whole system.
