## External catalog-based materialized view rewrite

StarRocks supports building asynchronous materialized views on Hive catalogs, Hudi catalogs, and Iceberg catalogs, and transparently rewriting queries with them. External catalog-based materialized views support most of the query rewrite capabilities, but there are some limitations:

- Hudi or JDBC catalog-based materialized views do not support Union rewrite.
- Hudi or JDBC catalog-based materialized views do not support View Delta Join rewrite.
- Hudi or JDBC catalog-based materialized views do not support the incremental refresh of partitions.

## 基于 External Catalog 构建物化视图

StarRocks 支持基于 Hive Catalog、Hudi Catalog 和 Iceberg Catalog 的外部数据源上构建异步物化视图，并支持透明地改写查询。基于 External Catalog 的物化视图支持大多数查询改写功能，但存在以下限制：

- 基于 Hudi 和 JDBC Catalog 创建的物化视图不支持 Union 改写。
- 基于 Hudi 和 JDBC Catalog 创建的物化视图不支持 View Delta Join 改写。
- 基于 Hudi 和 JDBC Catalog 创建的物化视图不支持分区增量刷新。
