Hi,
I notice that in the wrapped namespace of core.cache, there is a has? function that checks the wrapped cache if it has an element or not. It does this by delegating to the underlying cache c/has? function of the wrapped cache.
For reporting purposes, I need to get the current size of the cache (with the caveat of course that the size could be approximate, given the particular nature of a particular cache - but approximation is fine).
Unfortuantely, a size or count function doesn't exist in the wrapped namespace, it only exists on the wrapped cache itself - thus doing:
(count @wrapped-cache)
does return the value.
It would be good, however, if there was also a similar function in the wrapped namespace, something like this (using size as the function name, but could be something else):
(defn size
[cache-atom]
(c/count @cache-atom)
The rationale being that having this function exposed in the wrapped namespace keeps the code consistent - i.e., whilst I can continue to do:
(count @wrapped-cache)
It would more preferrable to keep using the wrapped namespace (as I do with other operations, such as evict), i.e., something along the lines of:
(wrapped/size wrapped-cache)
Do you think this suggestion might be something that could be included in the wrapped namespace?
Thank you.
