我需要我的flink作业以指定的时间间隔从数据库中提取记录，并在处理后将其存档。我已经实现了sourcefunction来从数据库中获取所需的记录，并添加了sourcefunction作为streamexecutionenvironment的源。如何指定streamexecutionenvironment需要每隔10分钟使用sourcefunction从数据库获取记录？
源函数：

public class MongoDBSourceFunction implements SourceFunction<List<Book>>{

    public void cancel() {
        // TODO Auto-generated method stub
    }

    public void run(org.apache.flink.streaming.api.functions.source.SourceFunction.SourceContext
<List<Book>> context) throws Exception {

        List<Book> books = getBooks();

        context.collect(books);

    }

    public List<Book> getBooks() {
        List<Book> books = new ArrayList<Book>();

        //fetch all books from database     
        return books;
    }

}

处理器：

import org.apache.flink.streaming.api.environment.StreamExecutionEnvironment;

public class ArchiveJob {

    public static void main(String[] args) {

        final StreamExecutionEnvironment env = 
    StreamExecutionEnvironment.getExecutionEnvironment();

        env.addSource(new MongoDBSourceFunction()).print();
    }

}
