+Beware that when loading a large amount of data for one table, the underlying rust implementation will consume a lot of memory.

 #### Delta table partitioning
 A Delta table can be partitioned ([Hive-style partitioning](https://delta.io/blog/pros-cons-hive-style-partionining/)) by specifying one or more `partition` column hints. This example partitions the Delta table by the `foo` column:
