Question: Can Redis Store JSON?

Answer

Yes. The RedisJSON module provides JSON support for Redis. RedisJSON enables you store, update, and load JSON values in a Redis database, similar to any other Redis data type. 

Primary Features

• Full support for the JSON standard.
• Documents stored as binary data in a tree structure, allowing fast access to sub-elements.
• Typed atomic operations for all JSON value types.

Python Example

The code snippet below shows how to use RedisJSON with raw Redis commands from Python with redis-py:

import redis
data = {
   'dog': {
       'scientific-name' : 'Canis familiaris'
   }
}
r = redis.Redis()
r.json().set('doc', '$', data)
doc = r.json().get('doc', '$')
dog = r.json().get('doc', '$.dog')
scientific_name = r.json().get('doc', '$..scientific-name')
