Debunking 8 data layout myths: why Liquid Clustering outperforms partitioning

Liquid Clustering is a modern data layout approach that outperforms traditional Hive-style partitioning in lakehouse environments.

• •Hive-style partitioning requires users to commit to a fixed physical organization at table creation, leading to over-partitioning and small-file problems in 75%+ of cases
• •Liquid Clustering allows the engine to determine optimal file organization and permits clustering keys to be changed at any time without table rewrites
• •Debunks 8 myths including directory-pruning advantage, partition necessity for metadata operations, and high-cardinality column handling
• •Provides row-level concurrency for concurrent ETL instead of file-level, enabling multiple writers on the same table without conflicts
• •Real-world results show 7.7x query speedup at Arctic Wolf (51s to 6.6s for 90-day queries) and 138% write throughput increase at Bolt
