java - Apache Ignite : Continuous SQLFieldQuery -


i looking expose apache ignite cache , client application can access same. can see continuous query support in apache ignite version 1.9 - https://github.com/apache/ignite/blob/master/examples/src/main/java/org/apache/ignite/examples/datagrid/cachecontinuousasyncqueryexample.java

however not able find example how implement continuous sqlfieldquery.

public static void main(string[] args) throws exception {         system.out.println("run spring example!!");         ignition.setclientmode(true);         igniteconfiguration cfg = new igniteconfiguration();         cfg.setincludeeventtypes( evts_cache);         cfg.setpeerclassloadingenabled(true);         tcpdiscoverymulticastipfinder discoverymulticastipfinder = new tcpdiscoverymulticastipfinder();         set<string> set = new hashset<>();          set.add("serverhost:47500..47509");         discoverymulticastipfinder.setaddresses(set);          tcpdiscoveryspi discoveryspi = new tcpdiscoveryspi();         discoveryspi.setipfinder(discoverymulticastipfinder);          cfg.setdiscoveryspi(discoveryspi);          cfg.setpeerclassloadingenabled(true);         cfg.setincludeeventtypes(evts_cache);         ignite ignite = ignition.start(cfg);          cacheconfiguration<string, binaryobject> cacheconfiguration = new cacheconfiguration<>(cache_name);           ignitecache<string, binaryobject> cache = ignite.getorcreatecache(cacheconfiguration).withkeepbinary();           querycursor<list<?>> query = cache.query(new sqlfieldsquery("select field1 table1 field1='test'"));             list<list<?>> = query.getall();             (list<?> l : all) {                 system.out.println(l);             }       }

continuous queries predicate based, sql not supported here. can provide remote filter called every update on server side. updates satisfy filter, batched , sent subscriber, local listener invoked.
