The DCS Redis management console supports manually stopping and starting Redis nodes.
Why Should You Restart a Node?
l Configuration updates: When restarting a node, you can apply new configuration parameters, such as adjusting memory limits, modifying persistence policies, enabling or disabling certain features, etc. After restarting the node, these changes will apply.
l Fault recovery: When a Redis node fails or has an exception, restarting the node can fix the issue and make Redis available again. This can solve some temporary issues such as memory leakage, network connectivity interruptions, etc.
l Performance optimization: Restarting nodes can help optimize Redis performance. For example, reloading data to memory can improve the speed of reading data, or eliminate memory fragmentation caused by long-time operations and improve memory utilization.
