Hi, what's the infra behind this? What do you use to store events or only the count of them to generate the numbers?
Other question I have is, you seem to have returning visitors feature and as far as I understood, you store info in localStorage to be able to do that. I guess you're generating a uniq identifier to be able to that and store in the localStorage. Although it's not a cookie, semantically isn't kinda same thing? If you were to store those in cookies you would have needed to show cookie banner, but since it's in localStorage you don't have to?
- tipiirai 5y agoWe're using Nats (https://nats.io/ https://nats.io/) for event streaming and pub/sub. The sessions are aggregated in memory, then they go to Badger (https://github.com/dgraph-io/badger https://github.com/dgraph-io/badger), and finally the daily aggregates are easily distributable and immutable JSON files. We're setting a session identifier to sessionStorage and those id's are wiped out once the session is processed and leaves the server memory. We worked together with a privacy specialist to ensure this is not violating GDPR. Details on what/how we collect data is here: https://volument.com/privacy/ https://volument.com/privacy/
