                 URL: https://issues.jboss.org/browse/ISPN-8310
             Project: Infinispan
          Issue Type: Feature Request
            Reporter: William Burns
            Assignee: William Burns


We need a way to run a command for all data in the cache (while under a lock) but also return a value for the data processed.

There are a few different APIs we could do for this having a {{Cache<K, V>}}

blocking variant
{code}
<R> Map<K, R> evalAll(BiFunction<Cache<K, V>, ? super CacheEntry<K, V>, R> biFunction)
{code}

back pressure aware variant  - this would have to be a hot observer on subscribe
{code}
<R> Producer<R> evalAll(BiFunction<Cache<K, V>, ? super CacheEntry<K, V> R> biFunction)
{code}
