我在收集JSON的Nifi中获得了一些数据,但是它需要插入的表具有不同的格式。
我很难将JSON结构分解成更小的部分--第二个部分似乎是两三个部分的转变。有什么想法能让我进入下一步吗?

请测试它,让我知道如果有任何问题。
我们使用Golang实现了一个包含CRUD的REST API,在Update服务中,客户端可以发送部分JSON(包括更改的字段),我们需要处理这些更改对实体的更新。 逻辑上,我们需要通过Id从DB获取实体到结构,然后将有效载荷json解封到另一个结构并更新实体。 这是一个简单的例子,实际上它可能是一个嵌套的结构和嵌套的json,我们如何用golang或事件其他语言(如Java,.NET)来处理这种
我们要求当前在SOLR中索引的文档可能需要定期进行部分更新。更新可以是。添加新字段B。更新现有字段的内容。我们模式中的一些字段是存储的,其他的没有。 Solr4确实允许这样做,但必须存储所有字段。见Update a new field to existing document和http://solr.pl/en/2012/07/09/solr-4-0-partial-documents-updat
基本上,我要问的是给定一个正方形2D阵列和一个有效的补丁大小(2D子阵列的大小),我将如何做到这一点。最终,我不需要以任何方式存储子阵列,我只需要找到每个子阵列的中值并将它们存储在一个一维阵列中。中值和存储到新阵列对我来说很简单,我只是不知道如何处理原始2D阵列并正确拆分它。我已经尝试了几次,但一直出现越界错误。我有一个4x4: 我需要像这样拆分它 < code>[1,2] [3,4] [2,3]
问题内容: 如何使用NEST2部分更新记录? 我正在寻找一个模拟请求:POST / erection / shop / 1 / _update {“ doc”:{“ new”:“ 0”}} 而无需重新 创建新记录。不幸的是,我没有在www.elastic.co/guide/en/elasticsearch/client/net- api/current/index.html中找到有关更新的任何信息
问题内容: 我想做如下的部分更新。添加一些新字段,例如Bytes_In和Bytes_Out。并且还运行脚本来更新使用脚本从其他字段派生的字段。 脚本session-duration-script.groovy在/ config / scripts路径下。 当我运行上述更新查询时,出现此错误 请让我知道有办法实现这种更新。 问题答案: 由于错误状态,您不能同时使用和。我的建议是修改脚本,以添加所需的
问题是关于阿克卡演员图书馆。A想把一个大任务分成几个小任务,然后把它们的结果合并成一个“大”结果。这将给我更快的计算利润。如果较小的任务是独立的,则可以并行计算它们。 假设我们需要这样计算。函数非常耗时,因此在一个线程中多次使用它并不理想。 问题来了。 如何分派任务、收集结果,然后折叠它们,所有这些都使用akka actors?Akka已经提供了这样的功能,还是我需要自己实现?这种方法的最佳实践是
