Best practice to store and update Time-series data in an mongodb
I am using mongodb to store the data of a sensor. Sensor pushes the data via mqtt, and nodejs (loopback) is being used to persist data in mongodb.
following properties are required to be saved in a document.
{
"time": "2019-01-01T14:22:55.691Z",
"value1": 0,
"value2":50 (but value2 will be received after few minutes of value1)
}
Story: I am using ultrasonic sensor to check the water level in tank. when I turn on the water pump I save the value of water level as value1 and when I turn off the water pump I want to save it as value2, as there will be many documents so how I can update a document for value2? do I query the latest "time" property or any other better way?

The data you are storing is usually referred to as Time Series and there are many resources online, eg: mongodb.com/blog/post/…
