# Optimize GetColumnsExtendedAsync in Databricks via `DESC TABLE EXTENDED` ## Motivation Currently, `HiveServer2Statement.GetColumnsExtendedAsync` will make 3 thrift calls `GetColumns`, `GetPrimaryKeys` and `GetCrossReference` to get all the information and then join them into one result set. Now Databricks introduces a SQL `DESC TABLE EXTENDED <table> AS JSON` that will return all of these information in one query, this can save 2 extra roundtrips and improve the performance. ### Description ### Change ### Testing -- This is an automated message from the Apache Git Service.
