Databricks Partition Over at Anita Passarelli blog

Databricks Partition Over. Select col1, col2, last_value(col2) over (partition by col1 order by col2) as column2_last from values (1, 10), (1, 11), (1, 12), (2, 20), (2, 21), (2, 22); Implement liquid clustering to simplify data layout decisions and optimize query performance. The over clause of the window function must include an order by clause. Unlike the function dense_rank , rank will produce gaps in the ranking. The window frame clause specifies a sliding subset of rows within the partition on which the aggregate or analytics function operates. A partition is composed of a subset of rows in a table that share the same value for a predefined subset of columns called the partitioning. This article provides an overview of how you can partition tables on azure databricks and specific recommendations around when you. In snowflake i get the following results. Learn how to use replacewhere and dynamic partition overwrite modes to selectively overwrite data in delta lake tables.
