interesting, in my case I need the events to be inserted in a SQL db, even the real time ones. For instance, I receive Contacts data from Hubspot in realtime, I send those contacts over to Salesforce and I store them in Postgres. Why Postgres? Because we want to keep a history of the contacts, plus we will need to have 1 source of truth for customers data to fulfill various data privacy requirements. How about Kafka for such a use case? Let's say I receive maybe 10,000 contacts per day.
