To get all available keys in Redis, you can use the “KEYS” command. This command takes a pattern as an argument and returns all keys that match the pattern.
You can run the command in the redis-cli by typing:
$ redis-cli KEYS pattern
where “pattern” is the pattern you want to match. For example, to get all keys that start with “user:”, you can use the pattern “user:*”.
You can also use the scan
command which is more efficient than KEYS command for large data sets.
$ redis-cli SCAN 0 MATCH pattern
In python redis library
import redis
r = redis.Redis()
keys = r.scan_iter("pattern")
