Big Data (volume) and real-time information processing (velocity) are two important aspects of Big Data systems. At first sight, these two aspects seem to be incompatible. Are traditional software architectures still the right choice? Do we need new, revolutionary architectures to tackle the requirements of Big Data?
This presentation discusses the idea of the so-called lambda architecture for Big Data, which acts on the assumption of a bisection of the data-processing: in a batch-phase a temporally bounded, large dataset is processed either through traditional ETL or MapReduce. In parallel, a real-time, online processing is constantly calculating the values of the new data coming in during the batch phase. The combination of the two results, batch and online processing is giving the constantly up-to-date view.
This talk presents how such an architecture can be implemented using Oracle products such as Oracle NoSQL, Hadoop and Oracle Event Processing as well as some selected products from the Open Source Software community. While this session mostly focuses on the software architecture of BigData and FastData systems, some lessons learned in the implementation of such a system are presented as well.
