Anton Vinogradov updated IGNITE-425: ------------------------------------ Comment: was deleted (was: [~NIzhikov], Bench should be refactored 1) We should wait for event/ We interested in time between put and event) > Introduce transformers for continuous queries > --------------------------------------------- > > Key: IGNITE-425 > URL: https://issues.apache.org/jira/browse/IGNITE-425 > Project: Ignite > Issue Type: Sub-task > Components: cache > Affects Versions: 2.2 > Reporter: Yakov Zhdanov > Assignee: Nikolay Izhikov > Priority: Major > Fix For: 2.5 > > > Currently if updated entry passes the filter, it is sent to node initiated > the query entirely. It would be good to provide user with the ability to > transform entry and, for example, select only fields that are important. This > may bring huge economy to traffic and lower GC pressure as well. > Possible signatures will be: > {noformat} > public final class ContinuousQuery<K, V, T> {..} // T is a type transformer > transforms to > public ContinuousQuery<K, V, T> setLocalListener(Listener<T> locLsnr) {..} // > Probably, we will have to introduce new listener type, since user may want to > wipe out key as well. > /* new method to add */ > public ContinuousQuery<K, V, T> setRemoteTransformerFactory(Factory<? extends > ContinuousQueryTransformer<K, V, T>> factory) { ..} > {noformat} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
