avimas opened a new pull request #6865:
URL: https://github.com/apache/pulsar/pull/6865
Batch size is not limited to the minimum of the maxNumberOfMessages and
maxSizeOfMessages from the BatchRecieve policy.
Reproduce the issue:
public void test() throws PulsarClientException {
final String topic = "persistent://my-property/my-ns/test";
Producer<byte[]> producer =
pulsarClient.newProducer().topic(topic).blockIfQueueFull(true).create();
new Thread(() -> {
while (true) {
producer.sendAsync("".getBytes());
}
}).start();
Consumer<byte[]> consumer = pulsarClient.newConsumer()
.topic(topic)
.receiverQueueSize(1000)
.subscriptionName("test")
.batchReceivePolicy(BatchReceivePolicy.builder().maxNumBytes(1024*1024).maxNumMessages(100).timeout(1,
TimeUnit.SECONDS).build())
.subscribe();
while (true){
Messages<byte[]> msg = consumer.batchReceive();
System.out.println(msg.size());
}
}
Some of the batches will be greater than the 100
