clients/src/main/java/org/apache/kafka/clients/producer/KafkaProducer.java (line 254) <https://reviews.apache.org/r/36034/#comment143728> I think we do not need to create a varialbe here since it is only referenced once in the code. Instead we could just call the following in line 410: metrics.sensor("...").record(); clients/src/main/java/org/apache/kafka/clients/producer/internals/Sender.java (lines 399 - 402) <https://reviews.apache.org/r/36034/#comment143726> This metric may better be added in RecordAccumulator's registerMetrics() rather than in Sender. Also, the naming convention is not aligned with others, would better be "buffer-exhausted-rate". - Guozhang Wang On July 6, 2015, 9:54 p.m., Dong Lin wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
