Why is everyone talking about ClickHouse®?

ClickHouse has gained popularity due to its ability to handle Big Data effectively. It's an open-source columnar OLAP database known for its high insert rates and fast analytical queries. Its performance is attributed to features like column-oriented data storage, data compression functionality, vector computation engine, physical sparse indices, distributed query processing, and more. ClickHouse is ideal for organizations dealing with enormous structured datasets for analytics, reporting, and other purposes. However, it may not be suitable for everyone as it's designed primarily for OLAP operations and has some limitations like SQL 'like' but not quite SQL compatibility and lack of full-fledged transactions support.
