Redik is asking about RisingWave's approach to cluster upgrades and whether zero downtime is ensured. Yufan Song explains the reasons for not preferring rolling upgrades and suggests shutting down all compute nodes at once for a single recovery. Yingjun provides a workaround involving creating a new instance, migrating workload, and shutting down the old instance. The discussion also touches on the concept of zero downtime and user experience during upgrades.
