Liquid Clustering
Liquid Clustering is a Databricks data engineering capability, introduced 2024.
Delta Lake data-layout optimization that supersedes Z-ordering and Hive-style partitioning; clustering keys can evolve without rewriting existing data.
- It replaces both partitioning and Z-ordering, and unlike either you can change the clustering keys later without rewriting a single existing file - old ZORDER columns can even be reused as-is.
- Databricks now recommends it for all new tables, over both partitioning and Z-ordering.
Limitations: Clustering-on-write doesn't support source queries with filters, joins, or aggregations (DBR 15.1 and below); you can't create a liquid-clustered table via Structured Streaming write (DBR 15.4 LTS and below); and automatic liquid clustering and row-level concurrency aren't available for managed Apache Iceberg v2 tables.
