  <P>
    Cassandra Spring Data中的轻量级事务通过支持
    <a href="https://docs.spring.io/spring-data/cassandra/docs/current/api/org/springframework/data/cassandra/core/InsertOptions.html" rel="nofollow noreferrer">
      InsertOptions
    </A>
     上课或
    <a href="https://docs.spring.io/spring-data/cassandra/docs/current/api/org/springframework/data/cassandra/core/UpdateOptions.html" rel="nofollow noreferrer">
      UpdateOptions
    </A>
      - 例如，通过相应的构建器创建它的实例，
    <a href="https://docs.spring.io/spring-data/cassandra/docs/current/api/org/springframework/data/cassandra/core/InsertOptions.InsertOptionsBuilder.html" rel="nofollow noreferrer">
      InsertOptions.InsertOptionsBuilder
    </A>
    ，然后将其实例传递给相应的操作
     <code>
      insert
    </code>
     要么
     <code>
      update
    </code>
    。
  </p>
  <P>
    操作结果是从返回的WriteResult类的实例获得的
     <code>
      insert
    </code>
    /
     <code>
      update
    </code>
     通过调用
    <a href =“https://docs.spring.io/spring-data/cassandra/docs/current/api/org/springframework/data/cassandra/core/WriteResult.html#wasApplied--”rel =“nofollow noreferrer “>
      .wasApplied功能
    </A>
    。
