Getting Current Redis Version in Python (Detailed Guide w/ Code Examples)
Use Case(s)
The most common use case for getting the current version of Redis using python is to ensure compatibility with the application code. Redis might introduce new features or deprecate old ones in different versions, so it's crucial to know the version currently running.
Code Example
We can get the Redis server version by connecting to it and then using the INFO command. Here's how you can do it using the redis-py library:
CODE_BLOCK_PLACEHOLDER_0
In this example, we first establish a connection to the Redis server and then use the info() function to fetch various information about the server as a dictionary. The current Redis version is stored under the redis_version key in that dictionary.
Best Practices
- Always handle exceptions while connecting to the Redis server or fetching any info from it. In real-world scenarios, the server might be down or there might be network issues.
- Keep your Redis server updated to the latest stable version to take advantage of the latest features and security patches.
Common Mistakes
- Not specifying the correct host and port while establishing the connection could lead to failure in connecting to the Redis server.
FAQs
Q: What other information can I get using the info() function?
A: The info() function returns a lot of useful information like uptime in seconds, connected clients, memory usage, etc.
