redis-endpoint:port> set {key} {value}

Delete Key

redis-endpoint:port> del {key}

Key query and delete in batches

By default, Redis does not support deletion with patterns

redis-cli keys "*Program*" | xargs redis-cli del

Delete All

redis-endpoint:port> FLUSHALL

Check the number of keys

redis-endpoint:port> DBSIZE

Check the commands that are executed
