Our Avalon Big Data Application Service (ABAS) permits ODS-based measurement data management systems to connect to big-data resources. The implementation as a SPARK client defines interfaces for communication (and standardization) between our Avalon ODS Server and SPARK. While metadata operations remain within Oracle, thereby allowing the system to retain most of ODS’s management functionalities, the system redirects mass data operations to predefined jobs in SPARK. Therefore, ABAS provides a scalable and high-performing ODS system. Our current implementation works with Apache Parquet but is independent to the physical storage technology used.
