How Long Does It Take to Add GeminiDB Redis Nodes at the Same Time? What Are the Impacts on Services?

GeminiDB Redis nodes can be added at the same time, which can be completed within 5 minutes. Shared storage is used. After nodes are added, data does not need to be migrated, but slots are rebalanced. A retry mechanism is needed to avoid service interruptions due to a few seconds of jitter or latency.
