Duplicated Devices when burst MQTT measures and non provisoned Device

[AlvaroVega]

Component

WIth dev1 and APIKEY non provisoned device:

Sending MQTT measures:

$ mosquitto_pub -h localhost -t /json/APIKEY/dev1/attrs -m '[{"v": 55}]'  && mosquitto_pub -h localhost -t /json/APIKEY/dev1/attrs -m '[{"v": 45}]' 

This duplicates device.

But not when (with a small delay):

$ mosquitto_pub -h localhost -t /json/APIKEY/dev1/attrs -m '[{"v": 55}]'  && sleep 0.05 && mosquitto_pub -h localhost -t /json/APIKEY/dev1/attrs -m '[{"v": 45}]' 

Sending HTTP measures:

$ curl -i -X POST 'http://localhost:7897/iot/json?i=disp2&k=APIKEY' -d '{ "level": "33"}' -H 'content-type: application/json' & curl -i -X POST 'http://localhost:7897/iot/json?i=disp2&k=APIKEY' -d '{ "level": "44"}' -H 'content-type: application/json'

This duplicates device.

Possible solutions:

• Ensure unique mongo index: willl result in measures reject
• Check findAndCreate to ensure Store device as soon as possible
• A throttle queue
