@merlimat @AnonHxy @Jason918 For `CompositeByteBuf`, if the number of components in the buffer not exceeds `maxComponent`, it wound not resize/mem_copy. But if the capital is not enough and need a new component, all the components will merge(copy) into a new component. Here I use the default value of `maxComponent`, which is 16. Because I'm not sure what exact value to set. But on the whole, the buffer will be allocated lazily, which means fewer wasted memory. To some extent, it achieves the purpose of saving memory. To reduce mem_copy/resize, maybe we can calculate the certain value of `maxComponent` with `maxBatchSize`, is it required? -- This is an automated message from the Apache Git Service.
