Doubt about API Reference for Confluent REST V2 and V3

[martinher-ntt]

Hi,

I am doing an analysis on using kafka rest proxy via docker-compose.

In analyzing the documentation I came across the versioning of the V2 and V3 APIs.
Essentially in V2 there are the basic APIs for testing a simple process :

• consumer instance -> create topic (single partition) -> subscribe to topic (/subscription or /assignement) -> create records -> consumer read records

I have a doubt though, not explicit, about V3 that goes beyond the concept of open-source.
I would like to understand the real goal of this new version. For example, I would have expected to find an updated version of the API /records which is not there. However, in this version there are also APIs that are complementary to those already present on V2 such as updating the partitions of a topic.
From what I noticed there is more reliance on the cluster part, so I ask what are the goals of the V3 and what will be the future improvements?

Thank you.
