      Description

      Currently, a consumer has to set fetch size larger than the max message size. This increases the memory footprint on the consumer, especially when a large number of topic/partition is subscribed. By decoupling the fetch size from max message size, we can use a smaller fetch size for normal consumption and when hitting a large message (hopefully rare), we automatically increase fetch size to max message size temporarily.
