The Kafka config docs include default values for quantities in milliseconds and bytes, for example log.segment.bytes has default: 1073741824. Many readers won't know that that's 1GiB, so will have to work it out. It would make the docs more readable if we included the quantity in the appropriate unit in parenthesis after the actual default value, like this:
default: 1073741824 (=1GiB)
Similarly for values in milliseconds.
