Luis Araujo updated KAFKA-10334:
--------------------------------
Description:
I'm using transactions provided by Kafka Producer API in a Scala project built
with SBT. The dependency used in the project is:
{code:java}
"org.apache.kafka" % "kafka-clients" % "2.1.0" {code}
I followed the documentation and I was expecting that transactions fail when I
call *.commitTransaction* if some problem is raised when sending a message like
it's described in the
[documentation.|https://kafka.apache.org/10/javadoc/org/apache/kafka/clients/producer/KafkaProducer.html]
Unfortunately, when testing this behaviour using a message larger than the size
accepted by the Kafka broker/cluster, the transactions are not working properly.
I tested with a 3 Kafka broker cluster with 1MB message max size (default
value):
- when the message has 1MB, the transaction is aborted and an exception is
raised when calling *commitTransaction()*
- when the message is bigger than 1MB, the transaction is completed
successfully *without* the message being written. No exception is thrown.
As an example, this means that when I produce 9 messages with 1 KB and 1
message with 1.1MB in the same transaction, the transaction is completed but
only 9 messages are written to the Kafka cluster.
I tested this behaviour with Kafka version 2.1.0 and 2.3.0 in both Kafka
cluster and Kafka Producer API.
