Where to set maximum message size in Apache Kafka?

Question

In which file I can increase the maximum message size for Kafka? (I'm sending records of String, byte[] and when I send byte[] of 770kb Kafka does not send the message)

Answer 1

In kafka 0.11.0 following four config options need to be set

Broker config options (details) :

1. message.max.bytes - The largest record batch size allowed by Kafka.

2. replica.fetch.max.bytes - The number of bytes of messages to attempt to fetch for each partition.

Producer config options (details) :

1. max.request.size - The maximum size of a request in bytes. It is advisable to match this value with (message.max.bytes).

Consumer config options (details) :

1. max.partition.fetch.bytes - max number of bytes per partition returned by the server. should be larger than the max.message.size so consumer can read the largest message sent by the broker.
