+# Hudi External Table of Doris
+
+Hudi External Table of Doris provides Doris with the ability to access hdui
external tables directly, eliminating the need for cumbersome data import and
leveraging Doris' own OLAP capabilities to solve hudi table data analysis
problems.
+
+ 1. support hudi data sources for Doris
+ 2. Support joint query between Doris and hdui data source tables to perform
more complex analysis operations
+
+This document introduces how to use this feature and the considerations.
+

+## How to use
+
+### Create Hudi External Table
+
+Hudi tables can be created in Doris in two ways. You do not need to declare
the column definitions of the table when creating an external table, Doris can
automatically convert them based on the column definitions of the table in hive
metastore.
+
+1. Create a separate external table to mount the Hudi table.
+ The syntax can be viewed in `HELP CREATE TABLE`.
Review Comment:
What is the second way of creating Hudi table? I didn't see it in the doc.
