NPipeline.Connectors.DuckDB

DuckDB source and sink nodes for NPipeline - an embedded analytical database connector with native Parquet/CSV/JSON support, SQL queries, and high-performance Appender API.

Features

  • SQL-over-files - Query Parquet, CSV, and JSON files with full SQL (aggregations, joins, window functions)
  • Streaming-first - Source nodes stream rows via IAsyncEnumerable<T> with zero full-result buffering
  • High-performance writes - Sink nodes use DuckDB's native Appender API for ~1M+ rows/sec throughput
  • File export - Export pipeline data to Parquet/CSV via DuckDB's optimized COPY TO
  • Zero infrastructure - Embedded in-process database; no server, no containers
  • Auto-create tables - Tables are automatically created from your CLR types
  • Attribute mapping - Use [DuckDBColumn] for property-to-column mapping
  • DI support - Full IServiceCollection integration with named databases

Runtime Notes

  • NPipeline.Connectors.DuckDB depends on DuckDB.NET.Data.Full, so native DuckDB runtime binaries are included transitively.

Quick Start

// Read from a Parquet file with SQL
var source = DuckDBSourceNode<SalesRecord>.FromFile("data/sales.parquet");

// Query with SQL
var source = new DuckDBSourceNode<Metric>(null, """
    SELECT region, SUM(amount) as Total
    FROM read_parquet('sales/*.parquet')
    GROUP BY region
    """);

// Write with high-performance Appender
var sink = new DuckDBSinkNode<Order>(null, "orders");

// Export to Parquet
var sink = DuckDBSinkNode<Report>.ToFile("output/report.parquet");
