設(shè)計(jì)Redis數(shù)據(jù)庫(kù)結(jié)構(gòu)時(shí),需要考慮數(shù)據(jù)的類型、訪問(wèn)模式、持久化策略以及性能需求。以下是一些常見(jiàn)的設(shè)計(jì)原則和示例:
Redis支持多種基本數(shù)據(jù)類型:字符串(String)、列表(List)、集合(Set)、有序集合(Sorted Set)和哈希(Hash)。
SET user:1 name "Alice" age 30
GET user:1 name
LPUSH users "Bob" "Charlie" "David"
RPOP users
SADD users "Alice" "Bob" "Charlie"
SISMEMBER users "Bob"
ZADD scores 10 "Alice"
ZADD scores 20 "Bob"
ZADD scores 30 "Charlie"
ZREVRANGE scores 0 2
HSET user:1 name "Alice" age 30
HGET user:1 name
user:1:name
。HSET user:1 name "Alice" age 30 email "alice@example.com"
HSET user:2 name "Bob" age 25 email "bob@example.com"
LPUSH user:1:activity "login" "2023-10-01 10:00:00"
LPUSH user:1:activity "logout" "2023-10-01 12:00:00"
ZADD scores 100 "Alice"
ZADD scores 200 "Bob"
ZADD scores 300 "Charlie"
