我用 docker-compose 安装了 Orion、MongoDB、Cygnus 和 sth-comet。我CYGNUS_MONGO_DATA_EXPIRATION=60为天鹅座设置。
我创建了对 Orion 实体的订阅，但历史数据不会过期。我希望旧数据消失。
docker-compose.yaml 如下：
version: "3.5"
services:
# Databases - Orion uses Mongo-DB, Cygnus is persisting to Postgres
# Modified to use password authentication between mongoDB and Fiware Orion to improve security in docker.
mongo-db:

之前docker-compose up -d，我创建了以下目录：
- D b
- 配置
接下来，我设置了这样的订阅：
curl -X POST http://localhost:1026/v2/subscriptions -H 'Content-Type: application/json' -d @- <<EOF
{
"description": "Notify all context changes to Cygnus",
"subject": {
"entities": [
{
"idPattern": ".*"
}
]
},
"notification": {
"http": {
"url": "http://cygnus:5055/notify"
}
}
}
EOF
Oriong的日志是：

然后，我插入了以下实体：
curl localhost:1026/v2/entities -s -S -H 'Content-Type: application/json' -d @- <<EOF
{"id":"Room1","type":"Room","temperature":{"value":23,"type":"Float"},"pressure":{"value":720,"type":"Integer"}}
EOF
Orion 说（对不起，我失去了日志行的头部）：
subsrv=<none> | comp=Orion | op=logTracing.cpp[148]:logInfoRequestWithPayload | msg=Request received: POST /v2/entities, request payload (112 bytes): {"id":"Room1","type":"Room","temperature":{"value":23,"type":"Float"},"pressure":{"value":720,"type":"Integer"}}, response code: 201
然后，我更新了实体：
curl localhost:1026/v2/entities/Room1/attrs -s -S -H 'Content-Type: application/json' -X PATCH -d @- <<EOF
{"temperature":{"value":24,"type":"Float"},"pressure":{"value":730,"type":"Float"}}
EOF

我等了几分钟，再次更新了实体：
curl localhost:1026/v2/entities/Room1/attrs -s -S -H 'Content-Type: application/json' -X PATCH -d @- <<EOF
{"temperature":{"value":25,"type":"Float"},"pressure":{"value":740,"type":"Float"}}

最后，我打印出历史数据：
它显示历史表包含旧的更新。如何自动消除旧的？
