How to fix kafka.common.errors.TimeoutException: Expiring 1 record(s) xxx ms has passed since batch creation plus linger time

Question

I am using kafka_2.11-2.1.1 and Producer using spring 2.1.0.RELEASE.

I am using spring while I am sending the messages to Kafka topic my producer generates a lot of TimeoutExceptions

org.apache.kafka.common.errors.TimeoutException: Expiring 1 record(s) for COMPANY_INBOUND--19: 229 ms has passed since batch creation plus linger time

I am using below kafka producer settings

acks: 1
retries: 1
batchSize: 100
lingerMs: 5
bufferMemory: 33554432
requestTimeoutMs: 60

I tried many combinations (specially batchSize & lingerMs) but nothing worked. Any help please what should be the setting for above scenario.

Tried again with below configs ...but no luck same error

acks = 1
    batch.size = 15
    buffer.memory = 33554432
    client.id = 
    compression.type = none
    connections.max.idle.ms = 540000
    enable.idempotence = false
    interceptor.classes = []
    key.serializer = class org.apache.kafka.common.serialization.StringSerializer
    linger.ms = 0
    max.block.ms = 60000
    max.in.flight.requests.per.connection = 5
    max.request.size = 1048576
    metadata.max.age.ms = 300000
    metric.reporters = []
    metrics.num.samples = 2
    metrics.recording.level = INFO
    metrics.sample.window.ms = 30000
    partitioner.class = class com.spgmi.ca.prescore.partition.CompanyInfoPartitioner
    receive.buffer.bytes = 32768
    reconnect.backoff.max.ms = 1000
    reconnect.backoff.ms = 50
    request.timeout.ms = 120
    retries = 1

Second Time Run :

I treid different combinations nothing worked. Hence i thought it would be problem with network , SSL etc. So I installed and run the Kafka on the same machine where producer is running i.e. in my local computer.

I tried to run the producer again pointing to the local Kafka topics. But no luck same issue.

Below are configuration params used.

Facing same error : org.apache.kafka.common.errors.TimeoutException: Expiring 1 record(s) for inbound_topic--1: 69 ms has passed since batch creation plus linger time

Also tried batch.size 5 , 10 & 0 linger_ms 0 , 5 , 10 etc. request_time_out 0 , 45, 60, 120 , 300 etc.

Nothing working ...same error.

What else should I try , what could be the solution ?

How to avoid negative key generation

Yeah I set up local set up and print the log with partition info which shows as below

2019-07-03 02:48:28.822 INFO 7092 --- [lt-dispatcher-2] c.s.c.p.p.CompanyInfoPartitioner : Topic : inbound_topic Key = 597736248- Entropy Cayman Solar Ltd.-null-null-null Partition = -1 2019-07-03 02:48:28.931 ERROR 7092 --- [ad | producer-1] o.s.k.support.LoggingProducerListener : Exception thrown when sending a message with key='597736248- Entropy Cayman Solar Ltd.-null-null-null' and payload='com.spgmi.ca.prescore.model.Company@8b12343' to topic inbound_topic :

org.apache.kafka.common.errors.TimeoutException: Expiring 1 record(s) for inbound_topic --1: 104 ms has passed since batch creation plus linger time

My topics inbound_topic has two partitions as you see below C:\Software\kafka\kafka_2.11-2.1.1\bin\windows>kafka-topics.bat --describe --zookeeper localhost:2181 --topic inbound_topic Topic:inbound_topic PartitionCount:2 ReplicationFactor:1 Configs: Topic: inbound_topic Partition: 0 Leader: 0 Replicas: 0 Isr: 0 Topic: inbound_topic Partition: 1 Leader: 0 Replicas: 0 Isr: 0

But my producer seems to trying to send to Partition = -1.

My partition logic is as below

int p = (((String)key).hashCode() * Integer.MAX_VALUE) % numPartitions;
        logger.info("Topic : "+ topic + "\t Key = " + (String)key + " Partition = " + p );

On key i am doing hashCode(). What need to be corrected here to avoid this negative number partition number ? i.e. Partition = -1

What should be my partition key logic like ?

anyhelp highly appriciated.

Solution 1

The error indicates that some records are put into the queue at a faster rate than they can be sent from the client.

When your Producer sends messages, they are stored in buffer (before sending them to the target broker) and the records are grouped together into batches in order to increase throughput. When a new record is added to the batch, it must be sent within a -configurable- time window which is controlled by request.timeout.ms (the default is set to 30 seconds). If the batch is in the queue for longer time, a TimeoutException is thrown and the batch records will then be removed from the queue and won't be delivered to the broker.

Increasing the value of request.timeout.ms should do the trick for you.

---

In case this does not work, you can also try decreasing batch.size so that batches are sent more often (but this time will include fewer messages) and make sure that linger.ms is set to 0 (which is the default value).

Note that you need to restart your kafka brokers after changing any configuration parameter.

If you still get the error I assume that something wrong is going on with your network. Have you enabled SSL?

Solution 2

I fixed the earlier issue using returning a valid partition number.

thank you so much for your detailed explanation. I tried earlier with request.timeout.ms 120 and increased request.timeout.ms 120 but no use. Now I tried with linger.ms = 0 as you suggested but still getting same error ... fyi I updated the question.

Why should we restart your kafka brokers after changing any configuration parameters , there parameters are set out at Producer config , how changing them will impact Brokers configurations to restart them? really confused , can you plz throw more light ?

@Shyam I was talking about broker level configuration parameters (i.e. those in server.properties).
