> The kryo Output has some limitation
>   - The size of the data is limited. kryo write data to the buffer, it will throw the overflow exception if the data exceed the size
>   - The Output.toBytes() will copy the data to temporary buffer and output, it will  decrease the performance and introduce garbage collection.
> When I was tuning Spillable Data structure and Manage State. I create a mechanism to share and reuse the memory to avoid above problem.  And it can be reused in core serialization with small change. Please see jira: https://issues.apache.org/jira/browse/APEXMALHAR-2190
