rust-data-processing 0.2.2

Python bindings for rust-data-processing: schema-first CSV/JSON/Parquet/Excel ingestion into an in-memory DataSet.

rust-data-processing

Python bindings for the rust-data-processing crate: schema-first ingestion from CSV, JSON, Parquet, and Excel into an in-memory DataSet, with profiling, validation, Polars-backed pipelines, SQL, and Phase 2 JSONL export, privacy transforms and summaries, median, Arrow interop, and incremental ingest helpers.

Infographic: Phase 2 — Phase 1 flow plus export, privacy, median, Arrow, incremental ETL; JVM planned Phase 3.

Install

pip install rust-data-processing

Requires Python 3.10+.

Quick start

import rust_data_processing as rdp

schema = [
    {"name": "id", "data_type": "int64"},
    {"name": "name", "data_type": "utf8"},
]
ds = rdp.ingest_from_path("path/to/data.csv", schema, {"format": "csv"})
print("rows", ds.row_count())

report = rdp.profile_dataset(ds, {"head_rows": 50, "quantiles": [0.5]})
print("profile rows sampled", report["row_count"])

validation = rdp.validate_dataset(
    ds,
    {"checks": [{"kind": "not_null", "column": "id", "severity": "error"}]},
)
print("checks", validation["summary"]["total_checks"])

Phase 2 (export, privacy, JSONL, median, Delta handoff)

Copy-paste snippets: Phase 2 Python examples (Markdown in repo). These APIs are also summarized in API.md (section Export, privacy summaries, truncation (Phase 2)).
