Demo

This directory contains demo applications showcasing Hudi-rs APIs across different programming languages. The demos run on Docker Compose and also serve as integration tests in the CI pipeline (see .github/workflows/ci.yml).

Infrastructure

The demo infrastructure is defined in compose.yaml.

Test data copied from the crates/test are placed in Minio, providing COW and MOR tables at:

• s3://hudi-demo/cow/
• s3://hudi-demo/mor/
