Produce failed: Local: Queue full

[indsak]

I am trying to receive data from socket at 100MBps, each message nearly 7000 -7500 bytes, and publish these messages to Kafka topic with partition 0.

When i execute the program, after 3 min I get the error "Failed to produce to topic: Local: Queue full".
How can I overcome this? I am giving below the settings which I wrote in conf. What other settings should I include?

I may be receiving data at still higher rate. Does librdkafka supports this?

Below are the conf settings I have done in librdkafka.
rd_kafka_conf_set(conf, "bootstrap.servers", KAFKA_BROKER, errstr, sizeof(errstr));
rd_kafka_conf_set(conf, "queue.buffering.max.messages", "100000000", NULL, 0);
rd_kafka_conf_set(conf, "queue.buffering.max.ms", "40", NULL, 0);
rd_kafka_conf_set(conf, "queue.buffering.max.kbytes", "1000000", errstr, sizeof(errstr));
rd_kafka_conf_set(conf, "message.max.bytes", "100000000", errstr, sizeof(errstr));
rd_kafka_conf_set(conf, "max.request.size", "100000000", errstr, sizeof(errstr));
rd_kafka_conf_set(conf, "compression.codec", "snappy", errstr, sizeof(errstr));

I am using 1.9.0 librdkafka for Producer.
Apache Kafka version:
Operating system:RHEL 7.9

server.properties is as below

broker.id=0
message.max.bytes=41943552
port:9093
num.network.threads=3
num.io.threads=8
socket.send.buffer.bytes=102400
socket.receive.buffer.bytes=102400
socket.request.max.bytes=104857600
offsets.retention.minutes=360
num.partitions=1
num.recovery.threads.per.data.dir=1
offsets.topic.replication.factor=1
transaction.state.log.replication.factor=1
transaction.state.log.min.isr=1
log.retention.minutes=3
log.segment.bytes=1073741824
log.retention.check.interval.ms=300000
delete.topic.enable=true
zookeeper.connect=localhost:2181
zookeeper.connection.timeout.ms=18000
group.initial.rebalance.delay.ms=0

I have seen many posts with similar subjects. Tried out whatever I could, but still I get this error.

It may be that in 40 ms you're producing more that 1MB of data, try increasing queue.buffering.max.kbytes to a value double than the size of messages produced in 40 ms.

OK. Thank you. I will try this and will update

[indsak]

If I take calculation for 7000 bytes, in 40ms time 4.2MB data will be there for publishing.

I modified the conf as follows
rd_kafka_conf_set(conf, "queue.buffering.max.messages", "100000", NULL, 0);
rd_kafka_conf_set(conf, "queue.buffering.max.ms", "5", NULL, 0);
rd_kafka_conf_set(conf, "queue.buffering.max.kbytes", "2147483647", errstr, sizeof(errstr)); //maximum value

But still the same error.
Where am I going wrong?
Any help?

Any help regarding my query @edenhill ?
