Columns and vector instructions

Column DBMS help us solve the problem of fast data processing with column data display, compression of types and vectorization. At first, you may think that vectorization is applied only in column DBMS.

In fact, vectorization is everywhere in data engineering: NumPy, pandas, Apache Spark, Numba.

We will learn the basics of columns and vectorization. We will also explore where we may feel the power of vectorization and learn what prevents it from working effectively.
