The purpose of this paper is to articulate how the Kognitio Analytical Platform can dramatically add business value to a Hadoop Data Lake (HDL). Kognitio delivers ultra-fast high-concurrency SQL on Hadoop. Hadoop (HDFS file system) is becoming the de-facto repository for Data Lakes. By selecting Hadoop as the persistence engine, organizations can have a truly scalable repository for all of their Big Data requirements. In addition, the repository can also store the metadata, keys and pointers to the wide range of operational data which may be stored in business applications, data warehouses, files and legacy systems. HDL is therefore the beneficiary recipient of all of the cleansed, trusted, secure quality data that is available.
