Invalid value 10737418240 for configuration segment.bytes: Not a number of type INT

Hi,

I am trying to apply custom segment.bytes value to kafka topic as follows.

----
apiVersion: kafka.strimzi.io/v1beta1
kind: KafkaTopic
metadata:
  labels:
    strimzi.io/cluster: default
  name: myname
  namespace: data
spec:
  config:
    cleanup.policy: compact
    segment.bytes: 10737418240
  partitions: 3
  replicas: 2
  topicName: mytopicname
---

But I got this error on broker log.

2020-03-13 06:50:44,048 INFO [Admin Manager on Broker 2]: Invalid config value for resource ConfigResource(type=TOPIC, name='mytopicname'): Invalid value 10737418240 for configuration segment.bytes: Not a number of type INT (kafka.server.AdminManager) [data-plane-kafka-request-handler-2]

segment.bytes in my manifest file looks valid integer. What is wrong with this configuration?
Thank you.

Hi,

segment.bytes uses the Java int type, which has a maximum possible value of 2147483647 (2^31-1). So although 10737418240 is a valid number it's too big.

Kind regards,

Tom
