Fiware堆栈iotagent，Orion上下文代理与AWS DocumentDB而不是mongoDB的兼容性 [英] Fiware stack iotagent,Orion context broker compatibility with AWS DocumentDB instead of mongoDB

问题描述

任何人都可以确认AWS DocumentDB与Fiware GE的兼容性，例如iotagent，Orion上下文代理.fiware stack是否与DocumentDB完全兼容.在尝试之前，先寻找建议和要考虑的事情.

Can anybody confirm the AWS DocumentDB compatibility with Fiware GE's like iotagent,Orion context broker. Is fiware stack fully working with DocumentDB. Looking for a suggestions and things to be consider before attempting it.

谢谢ONR

推荐答案

由于AWS DocumentDB仅支持MongoDB的一个子集，因此肯定会有一些不兼容性.

Since AWS DocumentDB only supports a subset of MongoDB, there is definitely going to be some incompatibility.

以地理位置查询为例

curl -G -X GET \
  'http://localhost:1026/v2/entities' \
  -d 'type=Store' \
  -d 'georel=near;maxDistance:1500' \
  -d 'geometry=point' \
  -d 'coords=52.5162,13.3777'

这些内部依赖于当前不支持的MongoDB地理空间操作: https://docs.aws.amazon.com/documentdb/latest/developerguide/mongo-apis.html#mongo-apis-geospatial

Internally these rely on the MongoDB geospatial operations which are not currently supported: https://docs.aws.amazon.com/documentdb/latest/developerguide/mongo-apis.html#mongo-apis-geospatial

据我了解，物联网代理只是将Mongo-DB用作用于映射数据的简单内存存储，因此不会有任何问题.

In my understanding, the IoT Agents are just using Mongo-DB as a simple memory store for mapping data so would not have any issues.
