>
> 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:
