Let’s say I have this:
KStream<String, CallRecord>[] branches = allRecords .branch( (imsi, callRecord) -> "VOICE".equalsIgnoreCase(callRecord.getCallCommType()), (imsi, callRecord) -> "DATA".equalsIgnoreCase(callRecord.getCallCommType()), (imsi, callRecord) -> true ); KStream<String, CallRecord> callRecords = branches[0]; KStream<String, CallRecord> dataRecords = branches[1]; KStream<String, CallRecord> callRecordCounter = branches[2]; callRecordCounter .map((imsi, callRecord) -> new KeyValue<>("", "")) .countByKey( UnlimitedWindows.of("counter-window"), stringSerde ) .print(); Here I has 3 branches. Branch 0 is triggered if data is VOICE, branch 1 if data is DATA. Branch 2 is supposed to get triggered regardless of type all the type so that then I can count stuff for a time window. BUT the problem is branch is implemented like this: private class KStreamBranchProcessor extends AbstractProcessor<K, V> { @Override public void process(K key, V value) { for (int i = 0; i < predicates.length; i++) { if (predicates[i].test(key, value)) { // use forward with childIndex here and then break the loop // so that no record is going to be piped to multiple streams context().forward(key, value, i); break; } } } } Note the break. So the counter branch is never reached. I’d like to change the behavior of branch so that all predicates are checked and no break happens, in say a branchAll() method. What’s the easiest way to this functionality to the DSL? I tried process() but it doesn’t return KStream.
