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:
        jValue = json.loads(str(msg.value))
   except ValueError:

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 ?

Sorry, kafka is a third-party package, not part of the Python Standard Library.  Suggest you pursue this with the Kafka project:
