How often should tracking events be sent to tracking API

[theliuk]

Hi,
we'd like to build our own analytics without relying on third party services.
Our idea is to use Analytics as FE SDK, and we'd like to write our custom plugin to send analytics data to our API.
The question is: how often should the FE send analytics data to the API? We would like to buffer analytics events and send them in batches to spare some network traffic.
How often does Google Analytics (and other providers) do this data sync?

Thank you,

Luca

Depends on how your backend is configured to handle events but you can for sure batch event to send.

See the AWS pinpoint provider for an example

analytics/packages/analytics-plugin-aws-pinpoint/src/pinpoint/index.js

Lines 28 to 41 in 46392ce

	const queue = smartQueue(
	async (events, rest) => {
	events.forEach((event) => logger('> Queue event', event))
	const response = await pinpointPutEvent(events, {})
	logger('> Queue response', response)
	},
	{
	max: 10, // limit... event limit is 100 for pinpoint
	interval: config.flushInterval || 3000, // 3s
	throttle: true, // Ensure only max is processed at interval
	// onPause: (queue) => {},
	// onEmpty: () => {}
	}
	)
