How to get all keys in Redis
📣 Sponsor
In Redis, we use KEYS
to retrieve specific keys we’ve defined in our database. For example, if we’d created a Redis key like this:
set someKeyName someValue
Then we could get that value by using KEYS
like this:
KEYS someKeyName
Interestingly, Redis KEYS
support glob style patterns - so we can match many keys using text familiar to you if you’ve ever worked with regex. Here are some examples:
someK?y
- the question mark represents any one character - sosomeKqy
,someKay
,someKyy
, etc, are all valid.someK*y
- the asterisk represents any character including spaces - sosomeKy
is validsomeK[a-d]y
- to matchsomeKay
,someKby
,someKcy
orsomeKdy
.someK[ea]y
, - to matchsomeKey
orsomeKay
someK[^10]y
- where[^10]
means any number before 10 not including 10.someK[^e]y
- where[^e]
means any letter before e, but not including e.
This glob style pattern support also lets us retrieve all keys at once. Since the asterisk (*) or wild card symbol is supported, to retrieve all keys in redis at once, you only have to run KEYS *
:
KEYS *
If you have a lot of keys, this may not be what you want to do - but for certain use cases, it can be quite useful to retrieve all keys in Redis at once.
