# String Commands — Redis

Source: https://www.geekswithgeeks.com/en/redis/redis-strings-basics

> SET, GET, and atomic counters — the simplest Redis data type.

## SET & GET

Every Redis key maps to a value. A **string** value can hold text, JSON, or numbers.

```bash
SET user:1:name "Ada"
GET user:1:name
```

Output:

```
OK
"Ada"
```

## Atomic counters

`INCR`/`DECR` change a numeric string atomically — safe even with many clients hitting the same key at once.

```bash
SET page:views 0
INCR page:views
INCR page:views
INCRBY page:views 10
```

Output:

```
OK
(integer) 1
(integer) 2
(integer) 12
```

## 512MB limit

A single string value can hold up to 512MB — plenty for JSON blobs, but Redis isn't meant to store large files.
