Overview

In this guide, you can learn about time series collections in MongoDB, and how to interact with them in the MongoDB Go Driver.

Time series collections efficiently store sequences of measurements over a period of time. The collection consists of time series data with the following information:

Data collected over time
Metadata that describes the measurement
Date of the measurement

Example	Measurement	Metadata
Sales Data	Revenue	Company
Infection Rates	Amount of People Infected	Location

Create a Time Series Collection

Important

Time series collections require MongoDB 5.0 or later.

To create a time series collection, pass the following parameters to the CreateCollection() method:

The name of the new collection to create
The TimeSeriesOptions object specifying at least the time field

Example

The following example creates the spring_weather.march2022 time series collection with the temperature as the time field:

db := client.Database("spring_weather")
tso := options.TimeSeries().SetTimeField("temperature")
opts := options.CreateCollection().SetTimeSeriesOptions(tso)
db.CreateCollection(context.TODO(), "march2022", opts)

To check if you created the collection, send the "listCollections" command to the RunCommand() method:

Testing whether we created a time series collection.

command := bson.D{{"listCollections", 1}}
var result bson.M
	
commandErr := db.RunCommand(context.TODO(), command).Decode(&result)
if commandErr != nil {
	panic(commandErr)
}
output, outputErr := json.MarshalIndent(result, "", "    ")
if outputErr != nil {
	panic(outputErr)
}
fmt.Printf("%s\n", output)

Query a Time Series Collection

To query a time series collection, use the same conventions as you would for retrieving and aggregating data.
