KafkaConsumer's Javadoc [1] says: > There is no client-side buffering in read_committed mode.
And it also says: > timeout - The time, in milliseconds, spent waiting in poll if data > is not available in the buffer. If 0, returns immediately with any > records that are available currently in the buffer, else returns > empty. Must not be negative. [2] mentions receive.buffer.bytes. Does the buffer mentioned in KafkaConsumer's Javadoc means the same thing as receive.buffer.bytes?
