I find the root cause is that: Doris catalog uses MySQL protocol to load Doris metadata, but MySQL doesn't support array data type, so Doris converts the array type to varchar in MySQL protocol. (The logic can be found in [Doris source codes](https://github.com/apache/doris/blob/39d1acdc5eb633d7ea2fe5cd4f9d3433ced372a7/fe/fe-common/src/main/java/org/apache/doris/catalog/PrimitiveType.java#L950-L1000)) Currently Doris does not provide a dedicated JDBC Driver, so we cannot retrieve array types from Doris through JDBC. Perhaps all we can do is to document it. -- This is an automated message from the Apache Git Service.
