Mule批处理作业花费太长时间来充实数据

我试图丰富数据以创建一个XML文件

第一个查询通过分组获得事务头

第二个查询从同一个文件中获取与头匹配的所有记录（详细信息），以丰富消息

问题是，运行丰富数据的查询大约需要一秒钟的时间。我需要为184764个头运行这个过程。在每个页眉一秒钟时，此作业将花费太长时间。有没有一种方法可以完成同样的事情而不必查询数据库中的详细信息？是否可以先加载所有记录，然后从内存中获取详细信息？代码如下：

    <db:generic-config name="Generic_Database_Configuration" url="${db.url}" 
driverClassName="${driver.class.name}" doc:name="Generic Database 
Configuration"/>

transformationGraphPath="list_map__to_list_map_.grf" 
doc:name="List_Map__To_List_Map_"/>
<data-mapper:config name="List_Map__To_XML_1" 
transformationGraphPath="list_map__to_xml_1.grf" 
doc:name="List_Map__To_XML_1"/>
