Clickhouse[1] is an open-source, column-oriented database management system (DBMS) designed for analytical processing of large volumes of data. It is specifically optimized for high-performance analytics on structured data and provides methods for efficient work with databases. For any database key hashing for strings is a very important methodology, helping to achieve better performance and make all system faster. There are a lot of improvements of basic single-thread hashing algorithms. In this paper, we will try to parallel them for multiple strings using SIMD(Single Instruction Multiple Data).
