Memcached get 命令

set a 0 0 1
1
set b 0 0 1
2
get a b

STORED
STORED
VALUE a 0 1
1
VALUE b 0 1
2
END

Fetching many keys in one get saves round-trips. Each VALUE echoes flag and length so the client knows how to parse the value (e.g. choose deserialization by flag).

set a 0 0 1
1
set b 0 0 1
2
get a b

STORED
STORED
VALUE a 0 1
1
VALUE b 0 1
2
END

一次 get 多个 key 比多次单 key 调用省网络往返。注意结果里每个 VALUE 都回显了 flag 和长度，程序据此解析值（如按 flag 决定反序列化方式）。
