What is INCR?
INCR command used to increment the value of a string key by 1. If the key does not exist, it initializes the key with a value of 0 before performing the increment operation, resulting in a value of 1. If the key contains a non-integer value, the command will return an error. INCR is atomic, meaning it is safe to use in concurrent environments without race conditions, making it ideal for use cases like counters or tracking metrics.
