Data Lake Training using Python

May 22,2017 | Posted by : Melissa Ricahrdson

In this 3 day training course, we’ll describe how a data lake is much more than a few servers cobbled together: it takes planning, discipline, and governance to make an effective data lake. And we’ll do it using Python.

Data lakes are emerging as an increasingly viable solution for extracting value from big data at the enterprise level, and represent the logical next step for early adopters and newcomers alike. The flexibility, agility, and security of having structured, unstructured, and historical data readily available in segregated logical zones brings a bevy of transformational capabilities to businesses.

What many potential users fail to understand, however, is what defines a usable data lake. Often, those new to big data, and even well-versed Hadoop veterans, will attempt to stand up a few clusters and piece them together with different scripts, tools, and third-party vendors. This method is neither cost-effective nor sustainable.
