Re: [infinispan-dev] Continuous Query Caching

Hi, Again, this is a feature from Coherence[1]. Basic idea is to execute a query against the cache, and hold the result object. This result object will always have up to date query result; this means that whenever something is modified in the cache the result itself is updated.

Advantage: if one performs the same query very often(e.g. several times every millisecond) the response will be fast and the system will not be overloaded. E.g. Filter filter = new AndFilter(new EqualsFilter("getTrader", traderid), new EqualsFilter("getStatus", Status.OPEN)); ContinuousQueryCache cacheOpenTrades = new ContinuousQueryCache(cache, filter); Iterator iter = cacheOpenTrades.entrySet().iterator(); //*this entrySet call will be instant!* FOr a full list of scenario in which this can be used take a look at [1]. Shall we consider adding something similar?
