----------------------------
Summary: Kafka Python Consumer library messages gets truncated
Key: KAFKA-3793
URL: https://issues.apache.org/jira/browse/KAFKA-3793
Project: Kafka
Issue Type: Bug
Reporter: Rahul
Snippet code is below:
from kafka import KafkaConsumer
from kafka.client import KafkaClient
from kafka.consumer import SimpleConsumer
consumer = KafkaConsumer('eventdetails_ingestion' ,
group_id='1',bootstrap_servers=‘xxxx:9092', max_partition_fetch_bytes=10555555)
for msg in consumer:
try:
jValue = json.loads(str(msg.value))
except ValueError:
fileErr.write(str(msg.value)+"\n")
Steps:
We send/produce large sets of messages to Kafka of around 20 to 30 KB size each
messages in JSON format and producing around 200 messages / sec for 1 hour
duration. We have 3 Kafka Brokers running and I am trying to consume the
messages from these 3 Kafka Brokers from the same topic using the above code.
The problem is that sometimes some of the messages gets truncated, I am not
sure why it happen ?
