[infinispan-issues] [JBoss JIRA] (ISPN-5222) Perform Remote Filtering/Conversion in a single step

Perform Remote Filtering/Conversion in a single step ---------------------------------------------------- Key: ISPN-5222 URL: https://issues.jboss.org/browse/ISPN-5222 Project: Infinispan Issue Type: Feature Request Components: Listeners Affects Versions: 7.1.0.Final Reporter: Stylianos Koussouris Assignee: Galder Zamarreño Fix For: 7.2.0.Final I want to have filter and convert take place in one step ie. do filtering and conversion applied to REMOTE LISTENERS in one step a) I define CacheEventConverterFactory which implements CacheEventConverterFactory, Serializable b) I register on the server org.infinispan.notifications.cachelistener.filter.CacheEventConverterFactory the cache event converter which returns (CacheEventConverter<K, V, C>) new SharesDynamicFilterConverter(params); c) I then define CacheEventFilterFactory which implements CacheEventFilterFactory, Serializable { and returns(CacheEventFilter<K, V>) new SharesDynamicFilterConverter(params); d) The CustomeDynamicFilterConverter extends AbstractCacheEventFilterConverter<String, Share, ShareProgress> implements Serializable { and has the implementation of public Share filterAndConvert(String key, Share oldValue, Metadata oldMetadata, Share newValue, Metadata newMetadata, EventType eventType) { e) finally I define a listener binding it to the filter and converter @ClientListener(filterFactoryName = "custom-dynamic-filter", converterFactoryName = "custom-dynamic-converter", includeCurrentState = true) and register it along with params for the filter on the client side cache.addClientListener(listener, new Object[]{"NYX", 50f}, null); The result of this is that certainly both accept and convert methods are run and both call the same filterAndConvert method on SharesDynamicFilterConverter However, this is not desirable as I don't want 2 steps which will effectively do the same thing but a single step. TBH I am not happy with the solution but what I did (in absence of better understanding of how to combine the steps -NOTE there is no single Factory for both Converter and Filter and even if it did we would probably have to implement accept & convert inside so the end result would have been the same) So what I did was to change the last step ie. e) finally I define a listener binding ONLY the converter @ClientListener(converterFactoryName = "murex-dynamic-converter", includeCurrentState = true) and register it along with params ONLY for the converter on the client side cache.addClientListener(listener, null, new Object[]{"NYX", 50f}); This works as it actually does the filter during the convert step BUT is there another way and am I missing something? If not this would be a feature request
