Best for real-time analytics on petabyte-scale data, scanning billions of rows per second. Rated 4.5/5 on G2, this open-source database is free.
ClickHouse works well when executing low-latency, sub-second queries on massive, columnar datasets. The friction starts when you attempt to join tables, which causes query performance to drop significantly, or when altering columns mid-stream silently disrupts data pipelines. Before buying, compare vs Snowflake, which natively supports complex multi-table joins and multi-row ACID transactions.
