pattern - 匹配的模式。 count- 最大查找的 entry 数 SCAN是一个基于游标的迭代器,每次调用该命令时,都会返回一个新的游标,需要在下一次调用时将其作为游标参数,以此完成对全局哈希表的迭代。 所以,scan不会比 keys 操作快, 时间复杂度是相同的。不同的是scan基于游标,他每次只选取 哈希表中的一部分遍历,分段...
The key patterns specified with this flag will be found using SCAN. Use this option if you need glob pattern matching; check-single-keys is faster for non-pattern keys. Warning: using --check-keys to match a very large number of keys can slow down the exporter to the point where it ...
The specified LUA regexes are applied to each key in the specified order, and the group name that a given key belongs to will be derived from concatenating the capture groups of the first regex that matches the key. For example, applying the regex^(.*)_[^_]+$to the keykey_exp_Nickwo...
