Yun Gao commented on FLINK-16009:
---------------------------------
I will first perform some experiments to show if reducing the size of values
(but may with some computational overhead) could improve the overall
throughput.
> Native support for the Variable-length and Zig-zag Variable-length integers

> Key: FLINK-16009
> URL: https://issues.apache.org/jira/browse/FLINK-16009
> Project: Flink
> Issue Type: Improvement
> Components: API / Type Serialization System
> Reporter: Yun Gao
> Priority: Major
>
> Currently Flink only support fixed-length integers. However, in many cases
> the values of the integer fields tend to be small, and we could reduce the
> size of serialized values by using [Variable length
> encoding|https://developers.google.com/protocol-buffers/docs/encoding#varints]
> and [Zig-zag variable-length
> encoding|https://developers.google.com/protocol-buffers/docs/encoding#signed-integers].
