 This document introduces the general configuration and usage of the JDBC Catalog. For different JDBC sources, please refer to the respective documentation.
 
+:::info Note
+The JDBC Catalog feature in Doris relies on the Java layer to read and process data, and its overall performance can be affected by the JDK version. Some internal libraries in older versions of the JDK (such as JDK 8) are less efficient and may lead to higher resource consumption. If higher performance is required, it is recommended to use Doris 3.0, which is compiled with JDK 17 by default and offers better overall performance.

 ## Applicable Scenarios
 
 The JDBC Catalog is only suitable for data integration, such as importing small amounts of data from a data source into Doris or performing join queries on small tables in a JDBC data source. The JDBC Catalog cannot accelerate queries on the data source or access large amounts of data at once.

+:::info 备注
+Doris 的 JDBC Catalog 功能依赖 Java 层读取和处理数据，整体性能在一定程度上会受到 JDK 版本的影响，比如一些内部库的实现在老版本 JDK（如 JDK 8）中效率较低，可能会导致资源消耗偏高。如果对性能有更高要求，推荐使用 Doris 3.0 版本，由于默认使用 JDK 17 编译，整体性能更优。

 ## 适用场景
 
 JDBC Catalog 仅适用于数据集成，如将少量数据从数据源导入到 Doris 中，或对 JDBC 数据源中的小表进行关联查询。JDBC Catalog 无法对数据源进行查询加速，或一次性访问大量数据。
