CERN on Real-Time Processing of Big Data with ScyllaDB

In a seminar, Miguel Martinez Pedreira from CERN and Glauber Costa from ScyllaDB discussed the use of ScyllaDB for real-time processing of big data in the ALICE experiment at CERN, focusing on its application to the AliEn Global File Catalogue. This catalogue, a comprehensive metadata index of files from the experiment, spans 80 computer centers across five continents and requires efficient handling of real-time data. ScyllaDB, known for its close-to-the-hardware architecture, enabled CERN to achieve high throughput and low latency while maintaining tight control over total cost of ownership (TCO). The transition from Cassandra to ScyllaDB in this context demonstrated significant improvements in processing capabilities, as highlighted in their video presentation.
