Re: Kafka broker slow down when consumer try to fetch large messages from topic
Hi Thanks for the information . I have one question : Right now in my scenario maximum message size is around 800KB . did we consider these messages in large size categories , because article told about 10-100 MB data .

Kafka broker slow down when consumer try to fetch large messages from topic
I have 4 node kafka broker with following configuration : Default Number of Partitions : num.partitions : 1 Default Replication Factor : default.replication.factor : 1 Maximum Message Size : message.max.bytes : 10 MB Replica Maximum Fetch Size : replica.fetch.max.bytes : 10 MB Right now I have 4 topic with 1 partition and 1 replication factor . "Topic Name" : "Broker Id" : "Total Messages Received Across Kafka Broker" : "Total Bytes Received Across Kafka Broker" Topic 1 - Leader Kafka Broker 1 : 4.67 Message/Second : 1.6 MB/second Topic 2 - Leader Kafka Broker 2 : 4.78 Message/Second : 4.1 MB/second Topic 3 - Leader Kafka Broker 1 : 4.83 Message/Second : 1.6 MB/second Topic 4 - Leader Kafka Broker 3 : 4.8 Message/Second : 4.3 MB/second Message consist of . when consumer tried to read message from "Topic 2" Kafka Broker rate of message receiving slow down from 4.77 message/second to 3.12 message/second , after some time try to goes up . I also attached screenshot of "Total Messages Received Across Kafka Broker" and "Total Bytes Received Across Kafka Broker" for topic "Topic 2" . can someone explain why it is happen and how to solve it ? Regards Prateek

Facing Issue to create asyn producer in kafka 0.8.2
Hi
I want to create async producer so i can buffer messages in queue and send
after every 5 sec .
my kafka version is 0.8.2.0.
and i am using kafka-clients 0.8.2.0 to create kafka producer in java.
below is my sample code :
package com.intel.labs.ive.cloud.testKafkaProducerJ;
import java.nio.charset.Charset;
import java.util.HashMap;
import java.util.Map;
import org.apache.kafka.clients.producer.KafkaProducer;
import org.apache.kafka.clients.producer.Producer;
import org.apache.kafka.clients.producer.ProducerConfig;
import org.apache.kafka.clients.producer.ProducerRecord;
import org.apache.kafka.common.Metric;
import org.apache.kafka.common.MetricName;
import org.apache.kafka.common.serialization.Serializer;
import org.apache.kafka.common.serialization.StringSerializer;
import org.apache.kafka.common.serialization.ByteArraySerializer;
import java.nio.file.DirectoryStream;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
public class TestKafkaProducer {
Map props = new HashMap();
props.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, metadataBroker);
props.put("producer.type", "async");
props.put("queue.buffering.max.ms", "5000");
Serializer keySerializer = new StringSerializer();
Serializer valueSerializer = new ByteArraySerializer();
producer = new KafkaProducer(props, keySerializer,
valueSerializer);
ProducerRecord imageRecord;
while ( true ) {
imageRecord = new ProducerRecord(topicName,
recordKey,imageBytes);
producer.send(imageRecord);
}
}
size of my message is around 77K
but its work like a synchronous producer , send every message to broker .
not buffering a message in to queue and send after 5 sec
please help to find out a solution.

facing issue in async producer application
Hi
I want to create producer in async mode so i can send message in 5 sec
interval.
below is my code :
Map props = new HashMap();
props.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG,
metadataBroker);
// props.put(ProducerConfig.ACKS_CONFIG, "0"); // don't wait
for ACKs
props.put("producer.type", "async"); // don't wait for ACKs
props.put("queue.buffering.max.ms", "5000"); // don't wait
for ACKs
Serializer keySerializer = new StringSerializer();
Serializer valueSerializer = new
ByteArraySerializer();
producer = new KafkaProducer(props,
keySerializer, valueSerializer);
ProducerRecord imageRecord;
imageRecord = new ProducerRecord(topicName,
recordKey,imageBytes);
producer.send(imageRecord);
