Introduction

In FLIP-1, we have defined the most basic primitive of DataStream V2. On this basis, this FLIP will further answer several important questions closely related to it:

1. How to configure the processing over the datastreams, such as setting the parallelism.
2. How to get access to the runtime contextual information and services from inside the process functions.
3. How to work with processing-time timers.

Public Interfaces

Briefly list any new interfaces that will be introduced as part of this proposal or any existing interfaces that will be removed or changed. The purpose of this section is to concisely call out the public contract that will come along with this feature.
