Feature Request: Support Clustering in hudi-rs

[CTTY]

Feature Description

Clustering is a core optimization feature in Apache Hudi, widely used to manage small files and improve query performance.

I’d love to see support for clustering in hudi-rs, which could handle this efficiently thanks to Rust’s performance. This would enable production-grade optimization workflows in native Rust pipelines.

Why this matters

• Performance: Rust is expected to make compute-intensive operations like clustering much more performant
• Ease of migration: Users who are using standalone clustering should be able to migrate to hudi-rs clustering easily
• Ecosystem trend: Similar efforts are emerging in other formats, e.g. Iceberg compaction.

Suggested Scope

Initial support might include:

• Reading clustering plans
• Executing clustering as a standalone action
• Supporting inline clustering in write paths (optional follow-up)

Prerequisites

• hudi-rs doesn't have write support overall, it needs to be able to write and commit data before we implementing complicated table services
