I guess you talk about hard failures or replication slot deletion, right? Debezium has a snapshot mode (1) to refetch everything from scratch, we have tested it but opted out of using it because it would put pressure on postgres with the queries on huge tables and on kafka and its storage. Imo we prefer to manually rebuild the clickhouse tables via postgres snapshots and latest cdc data, but there might be better options or ideas.
