Amazon Redshift introduces AZ64, a new compression encoding for optimized storage and high query performance

Source: AWS AZ64, a proprietary compression encoding that is designed to achieve a high compression ratio and improved query performance, is now available. Innovations in the AZ64 algorithm efficiently compress small groups of data values and leverage SIMD instructions for data parallel processing. This encoding results in significant storage savings in most cases relative to LZO and ZSTD encodings and optimal de-compression performance for numeric and date/time data stored in Amazon Redshift.
