How ordering nodes synchronize work

0 votes
Kafka keeps data only for 7 days. Suppose I shut down a ordered node for 7 days and turn it on after 7 days, how will the node sync with the network?

To prevent time-based retention and prevent expiring of data, kafka brokers are set with = -1. This means that the data is not erased after 7 days, it stays there even after and the entire transaction history is present.

When a new orderer service node(or a node that has been shut down for more than 7 days) is added, the kafka brokers
help them to synchronize work.
