Struct GeneratorConfig 

pub struct GeneratorConfig {
    pub scale_factor: f64,
    pub output_dir: PathBuf,
    pub tables: Option<Vec<Table>>,
    pub format: OutputFormat,
    pub num_threads: usize,
    pub parquet_compression: Compression,
    pub parquet_row_group_bytes: i64,
    pub parts: Option<i32>,
    pub part: Option<i32>,
    pub stdout: bool,
}

Configuration for TPC-H data generation

This struct holds all the parameters needed to generate TPC-H benchmark data. It’s typically not constructed directly - use TpchGeneratorBuilder instead.

Examples

use tpchgen_cli::{GeneratorConfig, OutputFormat};

// Usually you would use TpchGenerator::builder() instead
let config = GeneratorConfig {
    scale_factor: 10.0,
    ..Default::default()
};

Fields

scale_factor: f64

Scale factor (e.g., 1.0 for 1GB, 10.0 for 10GB)

output_dir: PathBuf

Output directory for generated files

tables: Option<Vec<Table>>

Tables to generate (if None, generates all tables)

format: OutputFormat

Output format (TBL, CSV, or Parquet)

num_threads: usize

Number of threads for parallel generation

parquet_compression: Compression

Parquet compression format

parquet_row_group_bytes: i64

Target row group size in bytes for Parquet files

parts: Option<i32>

Number of partitions to generate (if None, generates a single file per table)

part: Option<i32>

Specific partition to generate (1-based, requires parts to be set)

stdout: bool

Write output to stdout instead of files
