The process of inducting data from various source systems is called data acquisition. In our data lake, we have a layer defined (in fact, the first one) which has only this responsibility to take care of.
One of the main technologies that we see doing the main job of inducting data into our data lake is using Apache Sqoop. The following sections of this chapter aim at covering Sqoop in detail so that you get a clear picture of this technology as well as get to know the data acquisition layer in detail.
