GitHub user MarvinCai added a comment to the discussion: what is "滚动策略循环"?
Rollover means delete old(consumed) ledgers and make room for new ledgers. Ledger is append only and will not be writable once closed/fenced. Ledger can only be deleted as a whole, so all entries on a ledger has to be consumed and acked by consumers(or auto acked by ttl). Broker will scan ledger at background and if a ledger is fullly consumer(all entries are consumed) & (ledger exists more than configured retention period || total storage size for a topic cross max retion size), then it's marked for delete(rollover).
