> With KIP-182 we reworked Streams API largely and introduced a regression into 1.0 code base. If a KTable is populated from a source topic, ie, StreamsBuilder.table() -- the KTable does create its own changelog topic. However, in older releases (0.11 or older), we don't create a changelog topic but use the user specified source topic instead.
> We want to reintroduce this optimization to reduce the load (storage and write) on the broker side for this case.
