Cut your run time from minutes to seconds with HBase and Algebird

// 02.04.2015 // Data

[Note: Code for this demo is available here:] At MediaMath, our Hadoop data processing pipelines generate various semi-aggregated datasets based on the many terabytes of data our systems generate daily. Those datasets are then imported to a set of relational SQL databases, where internal and external clients query them in real time. When a query involves extra levels of aggregation on an existing dataset at run time, it starts to hog server resources, slowing down runtime. However, we have been able to reduce the query time on these terabyte–scale datasets from minutes to seconds by using a combination of […]
