Have you seen our technical deep dive on how ClickHouse works with Parquet files?

TL;DR: ClickHouse has been optimizing for Parquet for years. It can query Parquet files directly with no ingestion required, and it does it faster than many systems that can query their own native formats.

The post explores:
🔸 How ClickHouse parallelizes Parquet processing across CPU cores
🔸 Predicate pushdown techniques that minimize unnecessary I/O
🔸 Real-world benchmarks comparing Parquet to other formats

ClickHouse wasn't built specifically for the Lakehouse, but it is a perfect fit with first-class Parquet support and direct file querying capabilities.
