Advanced Producer settings

You may encounter some edge cases where these settings might help.


This sets the amount of memory the producer will use to buffer messages waiting to be sent to brokers. Consider the scenario where the producer is sending messages faster than the broker can handle. In that case, the records will remain buffered in the producer's memory. Each producer maintains a buffer memory of 32 MB, by default. This is called the send buffer. The buffer may fill up over time and fill back down when the throughput to the broker increases.

When the buffer memory is full, the producer's send() method will block. This is controlled by the producer setting

This parameter controls how long the producer will block when calling send() and when explicitly requesting metadata via partitionsFor(). Those methods block when the producer’s send buffer is full or when metadata is not available. When is reached, a timeout exception is thrown. The default value is 60000.
