Tell me about ClickHouse features, have you worked with it?

ClickHouse is an open-source columnar database management system designed for analytical queries and processing large volumes of data in real-time.

Features of ClickHouse:

• Columnar data storage, which speeds up aggregations and queries on large tables.
• High-speed data insertion and reading thanks to compression and efficient algorithms.
• Scalability and support for distributed clusters.
• Support for SQL-like syntax.
• Ability to work with time series and analytical functions.

I worked with ClickHouse for big data analytics, where high speed of aggregations and reporting was required. I used it for building dashboards and real-time monitoring, which significantly accelerated processing compared to traditional relational databases.
