Along with the growth of the dataset size, there is a steady requirement for high-performance associations/patterns mining algorithms.

With the introduction of Hadoop and other MapReduce-like platforms to the world, there is a chance to meet these requirements. I will discuss this further in the upcoming chapters. Depending on the size of the dataset, some algorithms should be revised and adjusted, such as the recursive algorithm that will eventually run out of space on the call stack and might present a challenge when converting to MapReduce.
