Question 1

How to install redis-py with hiredis for better performance?

Accepted Answer

Use pip install 'redis[hiredis]' to include the hiredis parser. This provides faster response parsing with minimal code changes, as detailed in the installation section. For most cases, it requires no additional configuration.

Question 2

redis-py vs redis-om-python: which one should I use?

Accepted Answer

Use redis-py for direct, low-level Redis command access and full control. Choose redis-om-python if you need high-level object mapping, data models, and ORM-like features, as recommended in the README for object mapping scenarios.

Question 3

How to set up a connection pool in redis-py?

Accepted Answer

Create a redis.ConnectionPool instance and pass it to the Redis client constructor. The README shows examples where each Redis instance gets its own pool, or you can define custom pools for shared resource management.

Question 4

How to use pub/sub in redis-py?

Accepted Answer

Call the pubsub() method on a Redis client to get a PubSub instance, then subscribe to channels and listen for messages. Note that publishing must be done from a separate Redis client, as explained in the advanced topics due to connection state limitations.

Question 5

Does redis-py support Redis 8 features like RESP3?

Accepted Answer

Yes, recent versions support Redis 7.2 to 8.2, including optional RESP3 protocol by setting protocol=3 in the connection. The README includes a code example for enabling RESP3 and notes compatibility with latest Redis releases.

Question 6

How to handle pipelining to batch commands?

Accepted Answer

Use the pipeline() method to create a Pipeline object, add commands with methods like set(), and execute them together with execute(). This reduces round-trip latency, as demonstrated in the basic pipelining example.

Question 7

Is redis-py compatible with Python asyncio?

Accepted Answer

Yes, but it requires using dedicated async clients like redis.asyncio.Redis, separate from the synchronous client. The README points to async connections in the advanced topics, but setup is more involved for asynchronous workflows.
