10.45Event replay

Suppose consumer is down for an hour.

What happens to events?

Questions:

does broker retain them?
how long?
can consumer resume?
is there replay ID / offset?

For Salesforce events, replay/resume concepts are important.

At interview level, say:

“For event-driven designs I'd verify retention and replay semantics so a consumer outage doesn't silently create data gaps.”

Strong answer.
