The 'TYPE' command in Redis is commonly used when you need to know the type of the key-value pair stored inside your Redis database. This can be helpful when debugging, or when dealing with a database where the data types aren't well-documented.
Let's assume you have installed redis-py
library and established a connection to your Redis server. Here’s how you can get the type of a specific key:
import redis r = redis.Redis(host='localhost', port=6379, db=0) key_type = r.type('your_key') print(key_type) # Outputs: set, list, zset, hash, string, or none (if key does not exist)
In this example, we're connecting to a Redis server running on localhost and then we use the type()
method provided by redis-py
to get the type of the key named 'your_key'. The returned value will be the data type of the key ('set', 'list', 'zset', 'hash', 'string') or 'none' if the key does not exist.
Dragonfly is fully compatible with the Redis ecosystem and requires no code changes to implement.
