Compare with:

increment(name, amount = 1, options = nil)

Cache Store API implementation.

Increment a cached value. This method uses the Redis incr atomic operator and can only be used on values written with the :raw option. Calling it on a value not stored with :raw will initialize that value to zero.

Failsafe: Raises errors.

Parameters

name req
amount opt = 1
options opt = nil
