Hilbert curves are used in modern data lakehouse storage optimisation techniques, such as Databricks' "liquid clustering" [1]. This can replace the need for more traditional "hive-style" partitioning, in which the data files are partitioned based on a folder structure (e.g. `mydatafiles/YYYY/MM/DD/`).
