Description

Motivation: Why do you think this is important?

In many cases, the index of array node in map tasks is needed, especially if the task is programmed to output a file with a static name that will be overwritten by subsequent array nodes. the index will help add a good name to that file for example and can be backtraced.

Goal: What should the final outcome look like, ideally?

In the returned current_context() value, a filed of node_index or a good name should be there representing the map_task index.

Describe alternatives you've considered

I generated a random id for each instance to distinguish which output came from which node.

Contributor guide

Research direction
Investigate the current context() function in Flyte's codebase, likely in the Python SDK or backend. Look for how map task indexing is handled. The issue requests adding a node index field to the context. Check existing PRs or discussions for implementation patterns. The maintainer may need to clarify the exact data structure.
