我想将数据从voltdb导出到kafka，但找不到相应kafka主题的任何更新数据。
voltdb部署.xml：

<export>
    <configuration target="archive" enabled="true" type="kafka">
        <property name="bootstrap.servers">s7biapp27:9092,s7biapp30:9092,s7biapp31:9092</property>
        <property name="topic.key">sobackup.voltdb_neweggpreso_1_</property>
        <property name="acks">0</property>
    </configuration>
</export>

voltdb流：

CREATE STREAM SOBACKUP EXPORT TO TARGET archive (
TIMESTAMP varchar(50),
YEAR varchar(4),
QUARTER varchar(10),
MONTH varchar(30),
WEEKGROUP varchar(30),
....
);

所以，请帮我找出哪里不对。是我的 deployment.xml ?
