High-Performance ETL for Apple Health XML Exports
This technical tutorial describes building a high-concurrency ETL engine to process very large Apple Health XML exports. The author outlines a performance-first architecture: a streaming Rust XML parser (quick-xml) to extract <Record> tags, export data as Apache Arrow record batches via PyO3 for zero-copy consumption in Python/Polars, and bulk-ingest cleaned data into ClickHouse using clickhouse-connect. The post includes code snippets for the Rust parser, Arrow-to-Polars bridge, ClickHouse table schema and bulk insert, and discusses production considerations such as parallelization, schema evolution, malformed XML handling, Grafana visualization, and feeding Arrow buffers into ML frameworks like PyTorch.
- Apple Health exports a single massive XML file containing millions of <Record> tags.
- The pipeline uses a streaming Rust parser (quick-xml) to avoid loading the entire XML into memory.
- Rust code is wrapped with PyO3 to return Apache Arrow tables for zero-copy consumption by Python/Polars.
