Amazon Redshift is a fast, scalable data warehouse that makes it simple and cost-effective to analyze all your data across your data warehouse and data lake. Redshift delivers ten times faster performance than other data warehouses by using machine learning, massively parallel query execution, and columnar storage on high-performance disk.
Three types of redshift. At least three types of redshift occur in the universe — from the universe’s expansion, from the movement of galaxies relative to each other and from “gravitational redshift,” which happens when light is shifted due to the massive amount of matter inside of a galaxy. This latter redshift is the subtlest of the three,
What came to be known as the cosmological redshift was the first piece of the Big Bang theory – and ultimately a description of the origin of our universe.
Amazon Redshift. Amazon Redshift is an Internet hosting service and data warehouse product announced in November 2012 which forms part of the larger cloud-computing platform Amazon Web Services. It is built on top of technology from the massive parallel processing (MPP) data-warehouse company ParAccel (later acquired by Actian ),
: a displacement of the spectrum of a celestial body toward longer wavelengths that is a consequence of the Doppler effect or the gravitational field of the source; also : a measurement of a celestial body’s redshift equal to the ratio of the displacement of a spectral line to its known unshifted wavelength and used especially to calculate the body
