Anastasiia Afanaseva

I am a Data Warehouse (DWH) developer with over 5 years of experience working with ClickHouse — a powerful columnar DBMS that has become my main tool for solving analytical tasks.

I want to share my experience using codecs in ClickHouse, talk about their pros and cons in real-world cases, and show how to balance between speed and storage efficiency. I hope my report will be useful for both beginners and experienced developers!
