数据湖探索 DLI

步骤6：发送数据和查询结果

使用Kafka客户端向步骤2：创建Kafka的Topic中的Topic发送数据，模拟实时数据流。

发送样例数据如下：

{"user_id":"0001", "user_name":"Alice", "event_time":"2021-03-24 08:01:00", "product_id":"0002", "product_name":"name1"}
{"user_id":"0002", "user_name":"Bob", "event_time":"2021-03-24 08:02:00", "product_id":"0002", "product_name":"name1"}
{"user_id":"0002", "user_name":"Bob", "event_time":"2021-03-24 08:06:00", "product_id":"0004", "product_name":"name2"}
{"user_id":"0001", "user_name":"Alice", "event_time":"2021-03-24 08:10:00", "product_id":"0003", "product_name":"name3"}
{"user_id":"0003", "user_name":"Cindy", "event_time":"2021-03-24 08:15:00", "product_id":"0005", "product_name":"name4"}
{"user_id":"0003", "user_name":"Cindy", "event_time":"2021-03-24 08:16:00", "product_id":"0005", "product_name":"name4"}
{"user_id":"0001", "user_name":"Alice", "event_time":"2021-03-24 08:56:00", "product_id":"0004", "product_name":"name2"}
{"user_id":"0001", "user_name":"Alice", "event_time":"2021-03-24 09:05:00", "product_id":"0005", "product_name":"name4"} 
{"user_id":"0001", "user_name":"Alice", "event_time":"2021-03-24 09:10:00", "product_id":"0006", "product_name":"name5"}
{"user_id":"0002", "user_name":"Bob", "event_time":"2021-03-24 09:13:00", "product_id":"0006", "product_name":"name5"}

登录RDS控制台，单击RDS数据库实例，单击创建的数据库名，如“testrdsdb”，在创建的表“clicktop”所在行的“操作”列，单击“SQL查询”，输入以下查询语句。
```
select * from `clicktop`;
```
在“SQL查询”界面，单击“执行SQL”，查看RDS表数据已写入成功。
