Amazon Redshift is a data warehouse product which forms part of the larger cloud-computing platform Amazon Web Services. [1] It is built on top of technology from the massive parallel processing (MPP) data warehouse company ParAccel (later acquired by Actian), [2] to handle large scale data sets and database migrations.
Using Hubble's law, the redshift can be used to estimate the distance of an object from Earth. By combining redshift with angular position data, a redshift survey maps the 3D distribution of matter within a field of the sky. These observations are used to measure detailed statistical properties of the large-scale structure of the universe.
A database shard, or simply a shard, is a horizontal partition of data in a database or search engine. Each shard may be held on a separate database server instance, to spread load. Some data in a database remains present in all shards, [a] but some appears only in a single shard. Each shard acts as the single source for this subset of data.
The AWS Redshift and RocksDB databases include support for field compression using Zstandard. [ 22 ] In March 2018, Canonical tested [ 23 ] the use of zstd as a deb package compression method by default for the Ubuntu Linux distribution.

The first redshift survey was the CfA Redshift Survey, started in 1977 with the initial data collection completed in 1982. [88] More recently, the 2dF Galaxy Redshift Survey determined the large-scale structure of one section of the universe, measuring redshifts for over 220,000 galaxies; data collection was completed in 2002, and the final ...
Amazon Relational Database Service (or Amazon RDS) is a distributed relational database service by Amazon Web Services (AWS). [2] It is a web service running "in the cloud" designed to simplify the setup, operation, and scaling of a relational database for use in applications. [ 3 ]
William G. Tifft was an astronomer at the University of Arizona.His main interests were in galaxies, superclusters and redshift quantization. [1] He was influential in the development of the first redshift surveys, and was an early proponent of crewed space astronomy, conducted at a proposed Moon base for example.
