Retrieval by Pattern

The SCAN command in Redis is a cursor-based iterator that does not guarantee to return all matching keys in one call, even if COUNT is specified. Instead, SCAN returns a small subset of keys that match the pattern, requiring subsequent calls to complete the iteration. Redis offers powerful pattern-based key retrieval, allowing users to query multiple keys using wildcard patterns. This functionality primarily relies on the KEYS command, which supports glob-style patterns such as *, ?, and [] for flexible matching.
