Flowthru.Extensions.Parquet

Read and write Flowthru Catalog Items as Parquet files. Adds the Parquet format to the Catalog builder, so any Item backed by a row sequence serializes to and from .parquet with a one-line declaration. Parquet is the format of choice for intermediate and primary data: it's binary, columnar, and compressed, so it round-trips large typed row sets far faster and smaller than CSV.

Mental model

Storage in Flowthru is three independent axes: format (how bytes serialize) × medium (where bytes live) × container (the in-memory shape). This package supplies one format — Parquet. Bring the columnar mental model: instead of one record per line, values are grouped by column into compressed row groups, so reads can skip columns and writes pack tightly. You don't manage any of that — you declare the Item, and Flowthru maps your schema to and from the columnar layout. It doesn't care where the .parquet lives (that's the medium's job).

Install

dotnet add package Flowthru.Extensions.Parquet

Declare a Parquet-backed Item in your Catalog:

public IItem<IEnumerable<PreprocessedShuttleSchema>> PreprocessedShuttles =>
    CreateItem(() => Item.Of<IEnumerable<PreprocessedShuttleSchema>>("PreprocessedShuttles")
        .Parquet()
        .AtPath($"{_basePath}/Data/_02_Intermediate/preprocessed_shuttles.parquet")
        .Build());

Defaults are Snappy compression, 1,000,000-row groups, and dictionary encoding. To tune them, pass .WithOptions(...).
