I submitted a pull request with some changes I tried to explain here.

There are still open questions for me regarding:
- better dependency mechanism
- updating dependency to the latest 3.1.0
- process flow in aggregate functions (avoiding overhead of pairwi
I am afraid that I was misunderstood regarding a few points. Let me try to
clarify.
Regarding serialization using bytes as opposed to a stream. This has
nothing to do with BINARY data type in Impala.

Hi，
1. Upgrade DataSketches to version 3.1.0
