Get the counter value: Use the GET command to get the current value. Increment counter: Use the INCRBY command, followed by the amount to be incremented. Decrement counter: Use the DECR or DECRBY command to decrement by 1 or specify the amount. Reset the counter: Use the SET command to set its value to 0. In addition, counters can be used to limit rates, session tracking, and create voting systems.
