Java BlockingQueue with batching?

Question

I am interested in a data structure identical to the Java BlockingQueue, with the exception that it must be able to batch objects in the queue. In other words, I would like

Answer 1

I recently developed this utility that batch BlockingQueue elements using a flushing timeout if queue elements doesn't reach the batch size. It also supports fanOut pattern using multiple instances to elaborate the same set of data:

// Instantiate the registry
FQueueRegistry registry = new FQueueRegistry();

// Build FQueue consumer
registry.buildFQueue(String.class)
                .batch()
                .withChunkSize(5)
                .withFlushTimeout(1)
                .withFlushTimeUnit(TimeUnit.SECONDS)
                .done()
                .consume(() -> (broadcaster, elms) -> System.out.println("elms batched are: "+elms.size()));

// Push data into queue
for(int i = 0; i < 10; i++){
        registry.sendBroadcast("Sample"+i);
}
