• I searched in the issues and found nothing similar.

Motivation

I propose to add SinkV2 implementation for Paimon Flink Sink.

With this new implementation, we can follow up on the optimizations made by Flink on Sink, and have a more reliable way of connecting with other ecosystem projects such as FlinkCDC or Seatunnel.
