Aggregate kernel consumes one batch and output a `state`, which is then merged with other batches. Currently, `state` parameter is defined as `const KernelState&` in `merge` interface. It may cause unnecessary data copying for kernels with non-trivial `states`. E.g., mode kernel maintains a value:count map in its `state` structure, by removing `const`, we can move the map rather than copy it. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
