 ## JDBC
 
+*NOTICE: CURRENTLY, JDBC IS USED FOR CONNECTING SOME THIRD-PART TOOLS. 
+IT CAN NOT PROVIDE HIGH THROUGHPUT FOR WRITE OPERATIONS. 
+PLEASE USE [JAVA NATIVE API](Programming-Native-API.md) INSTEAD*

 ## JDBC
 
+*注意: 目前的JDBC实现仅是为与第三方工具连接使用的。使用JDBC（尤其是执行插入语句时）无法提供高性能吞吐。
+对于Java应用，我们推荐使用[JAVA NATIVE API](Programming-Native-API.md) *
