Types

type Cache

type Cache interface {
	// 是否开启压缩。压缩后能减小数据量,但压缩过程会耗时。
	// 如果原数据长度很长,压缩耗时要比查询耗时低得多,此时开启压缩功能是最佳选择。
	// 但如果原数据长度较短,压缩或不压缩,整体耗时区别不大。
	// 是否开启压缩,需要自行测试抉择。
	Compressed(yes bool)
	// 初始化,用来迁移数据库 / 表,和一些与数据库有关的前期准备工作
	Init() error
	// 当前请求是否已缓存过,如果缓存过,则返回缓存中的响应
	IsCached(key string) ([]byte, bool)
	// 将没有缓存过的请求保存到缓存中
	Cache(key string, val []byte) error
	// 清除全部缓存
	Clear() error
}
