Efficient architectures for creating MapReduce Pipelines
by Fabiane Nardon, Java Champion and Big Data Expert
Crunching, aggregating, analyzing, transforming: real world data science applications usually perform several processing steps, each step adding more value to your data. Architecting and coordinating these processing pipelines in an efficient way requires a good understanding of the underlying mechanisms of MapReduce algorithms and a few tricks you only learn after you processed several terabytes. This presentation will show how to architect efficient MapReduce pipelines, how to integrate your pipelines with external datasources, like Redis, MongoDB or even relational databases, how to decide the best granularity for a job and when investing in a MapReduce architecture really pays off.
