The Hadoop ecosystem has a well-known hole: there is no good tool for near-real time analytics on Big Data. For example, suppose you have 500 milliseconds to calculate the average temperature reading from a set of sensors, based on some ad hoc user-specified criteria such as location, time and sensor type.

Last time we explored Massively Parallel Processing (MPP) databases as a way to run SQL queries on Big Data at Rest. One of the leading commercial products in this category is Pivotal’s Greenplum, which, at its peak, achieved annual revenues of over $100 million. The rise and fall of this product provides an illustrative lesson […]
read more »The first technology family we will explore for Big Data at Rest is Massively Parallel Processing (MPP). Traditional relational databases scale up by adding more server nodes, which share the same disks. Some databases, such as Oracle’s Real Application Cluster (RAC) go even further, and share the same in-memory cache across all servers. The benefit […]
