Effectively, using Redis in your application involves understanding how Redis stores keys and the operations to manipulate the key space within a Redis instance. Running a 32-bit or 64-bit version of Redis dictates the practical limits to the size of your Redis keys. For the 32-bit Redis variant, any key name larger than 32 bits requires the key to span multiple bytes, thereby increasing the Redis memory usage. Using 64-bit Redis allows for larger key lengths but has the downside that keys with small lengths will be allocated the full 64 bits, wasting the extra bits that are not allocated to the key name.

The flexibility of Redis allows for a wide diversity in how keys are structured and stored. The performance and maintainability of Redis can be either positively or negatively impacted by the choices made in designing and constructing the Redis keys used in your database.
