Why the consumer can't receve the message if fetch_size=1

["Honda Wei ( 魏宏達 )" <Ho...@taiwanmobile.com>]

Hi Kafka Team

I write some simple program and find a strange issue.
Why the consumer can’t receive the message if the fetch is set to 1 , but when the parameter set to 100.
The consumer will receive the message normally.

FetchRequest req = new FetchRequestBuilder()
        .clientId(clientName)
        .addFetch(a_topic, a_partition, readOffset, 100)
        .build();



Thanks~

Best Regards

The fetch request size should not be less than the maximum message size.
Apparently, all your messages are larger than 1 byte, so when you set fetch
size to 1, your consumer is unable to fetch anything.
