Question 1

How do I set up connection pooling in Redigo?

Accepted Answer

Use the redis.Pool type from the package; configure parameters like MaxIdle and MaxActive in the pool struct, then retrieve connections with pool.Get() for efficient management in concurrent apps. Refer to the connection pooling documentation for best practices.

Question 2

Redigo or go-redis: which should I choose?

Accepted Answer

Redigo offers a simpler, more idiomatic Go API with minimal dependencies, while go-redis provides more features out of the box like native cluster support and higher-level abstractions. Choose Redigo for lean, performant setups, or go-redis if you need built-in advanced functionality without extra libraries.

Question 3

How to execute Lua scripts with Redigo?

Accepted Answer

Use the redis.Script helper type; define your script as a string, create a Script instance, and call Do() or Send() on it. Redigo optimizes this with EVALSHA to cache scripts and reduce network overhead, as detailed in the script helper documentation.

Question 4

Does Redigo work with Valkey?

Accepted Answer

Yes, Redigo is compatible with Valkey since it's a Redis protocol-compatible client, so you can use it interchangeably for most commands without modifications. The README explicitly lists Valkey as a supported data store.

Question 5

What's the best way to mock Redigo for unit tests?

Accepted Answer

Use the redigomock library from rafaeljusto/redigomock, which is a related project mentioned in the README. It provides a mock implementation that integrates seamlessly with Redigo's interface, allowing testing without a real Redis instance.

Question 6

How to handle publish/subscribe in Redigo?

Accepted Answer

Create a dedicated connection using Conn, subscribe to channels with Subscribe(), and use Receive() in a loop to listen for messages. Note that pub/sub connections cannot execute other commands concurrently, as explained in the publish/subscribe documentation.
