Redis is an in-memory data structure store that can be used as a database, cache, and message broker. It provides high performance and scalability, making it ideal for use in modern web applications. Redis supports a wide range of data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, and geospatial indexes with radius queries.
Some of the key features of Redis are:
Here's an example of using Redis to store and retrieve data:
import redis # Connect to Redis r = redis.Redis(host='localhost', port=6379, db=0) # Set a value r.set('mykey', 'Hello World!') # Get a value value = r.get('mykey') print(value)
This code connects to a Redis instance running on
localhost and sets a value for the key
mykey. It then retrieves the value and prints it, which should output "Hello World!".
Dragonfly is fully compatible with the Redis ecosystem and requires no code changes to implement.
