Redis is often used to store key-value pairs where keys may have a common prefix that denotes some logical grouping. For instance, you might store user-related data with keys like
Sometimes you need to retrieve all keys starting with a specific prefix, such as
user:1 in this case, to perform operations on related data.
go-redis client provides powerful commands to interact with Redis. The
Keys command gets all keys matching a pattern.
This code connects to a local Redis instance, and retrieves all keys starting with
user:1. Please replace "user:1" with the actual prefix you are using.
Keyscommand in production environments for large databases because it may degrade performance. Use
Keyscommand in production which could lead to performance issues.
Q: Can I use this method to get keys using other patterns, not just prefixes?
A: Yes, the pattern argument in the
Keys can be any glob-style pattern supported by Redis.
