In this case study learn how Daitan’s Data Engineering team builds a near real-time analytics platform able to handle 15 billion Telco events (13 TBs) a day. Complexity of data comes in the form of sheer volume, data types and multiple sources. A platform to collect, transform, pre-process, aggregate and analyze this type of data demands frameworks of cluster-computing, high capacity data storage, messaging, searching, along with high availability and auto scaling capabilities
