Tool: `scan_all_keys`

Scan and return ALL keys matching a pattern using multiple SCAN iterations.

This function automatically handles the SCAN cursor iteration to collect all matching keys. It's safer than KEYS * for large databases but will still collect all results in memory.

⚠️ WARNING: With very large datasets (millions of keys), this may consume significant memory. For large-scale operations, consider using scan_keys() with manual iteration instead.

Parameters	Type	Description
`batch_size`	`integer`optional	Number of keys to scan per iteration (default 100).
`pattern`	`string`optional	Pattern to match keys against (default is "*" for all keys).

Tool: `scan_keys`

Scan keys in the Redis database using the SCAN command (non-blocking, production-safe).

⚠️ IMPORTANT: This returns PARTIAL results from one iteration. Use scan_all_keys() to get ALL matching keys, or call this function multiple times with the returned cursor until cursor becomes 0.

The SCAN command iterates through the keyspace in small chunks, making it safe to use on large databases without blocking other operations.

Parameters	Type	Description
`count`	`integer`optional	Hint for the number of keys to return per iteration (default 100).
`cursor`	`integer`optional	The cursor position to start scanning from (0 to start from beginning).
`pattern`	`string`optional	Pattern to match keys against (default is "*" for all keys).
