I like good data compression and fast query execution

Perfom and huge arsenal of Engines that helps you ingest and process data at scale. Like they have an Engine for almost all use case.

TLDR: Fast, Very Very Very Fast, Rich SQL, Good compression algorithms Detail: 1) Rich SQL syntax. There are a lot of in-build functions (including GeoDistances, Uber Hexagons support, time functions, comprehensive mah, and many others). Functions could be combined (e.g. with If: SumIf, AvgIf, etc) which is very convenient. 2) Fast. Arrays and MapReduce make CH working LIGHTNING FAST. I was extremely surprised when several GBs of data were processed in under 1 second. 3) Fast. Materialized Views work differently than in other databases, but the correct usage allows instant processing of TBs of data. 4) Efficient. Vast amount of data types and compression algorithms help you to store data extremely efficiently. Make sure to check the docs and choose the best compression types for your tables. You will be very surprised. Overall you see very smart engineers worked on this database. It was made by engineers for engineers.
