Overview ¶
Package csv provides CSV reading and writing for the dataset package.
This is a pure API facade — it contains zero heavy imports. The actual CSV parsing/writing is delegated to the engine via the dataset.CSVReader and dataset.CSVWriter interfaces:
- Memory engine: uses go-simdcsv + schema inference (dataset/memory/csv.go)
- Arrow engine: uses arrow/csv for zero-copy ingest (dataset/arrow/csv.go)
Usage:
ds, err := csv.Read(ctx, file, eng, csv.WithHeader(true)) err = csv.Write(ctx, file, ds, eng)
