> 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}
