clients/src/main/java/org/apache/kafka/clients/producer/internals/BufferPool.java <https://reviews.apache.org/r/18299/#comment68747> I changed the deallocation function to be one-at-a-time since currently no callers give it a list of buffers at a time. If we are not going to make BufferPool out of producer I think this change is OK. clients/src/main/java/org/apache/kafka/common/record/ByteBufferOutputStream.java <https://reviews.apache.org/r/18299/#comment68748> I doubled the space in re-allocation, but we can be also conservative. clients/src/main/java/org/apache/kafka/common/record/CompressionType.java <https://reviews.apache.org/r/18299/#comment68749> Personally I do not like this to be in CompressionType, but moving the init-rate to CompressionFactory also requires some awkwardness. Any suggestions are welcomed. clients/src/main/java/org/apache/kafka/common/utils/Utils.java <https://reviews.apache.org/r/18299/#comment68750> This function may not be best here, but I do not really have a better place to locate it. - Guozhang Wang On March 14, 2014, 8:54 p.m., Guozhang Wang wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
