LockedStream invokeAll ---------------------- Key: ISPN-8310 URL: https://issues.jboss.org/browse/ISPN-8310 Project: Infinispan Issue Type: Feature Request Reporter: William Burns Assignee: William Burns Fix For: 9.2.0.Alpha2 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> Publisher<R> evalAll(BiFunction<Cache<K, V>, ? super CacheEntry<K, V> R> biFunction) {code}
