Hi, Records are not sent out immediately, even if configing batch.size=0 and linger.ms=0, They are buffered in the memory(buffer.memory). I don't want to do sync writes by future.get, which performance is not good. Have any configure can increase sending frequency? config buffer.memory=0?
Thanks. Yuanjia Li From: Matthias J. Sax Date: 2017-03-02 01:42 To: users Subject: Re: when will the messsages be sent to broker There is also linger.ms parameter that is an upper bound how long a (not yet filled) buffer is hold before sending it even if it's not full. Furthermore, you can do sync writes and block until producer received all acks. But it might have a performance penalty. http://docs.confluent.io/current/clients/producer.html#synchronous-writes -Matthias On 3/1/17 6:55 AM, Kaufman Ng wrote: > By default producer batches records (into a buffer) until batch.size is > reached, then records will be sent out.
