Enum SamplingStrategy 

pub enum SamplingStrategy {
    Random,
    Systematic,
    Reservoir,
    Stratified,
    Temporal {
        column_name: String,
    },
    MultiStage,
}

Available sampling strategies for large databases

Variants

Random

Simple random sampling - fastest but may skip patterns

Systematic

Systematic sampling - every nth row

Reservoir

Reservoir sampling - single pass, memory efficient

Stratified

Stratified sampling - maintains class distribution

Temporal

Time-based sampling - for temporal data

Fields

column_name: String

MultiStage

Multi-stage sampling - first sample tables, then rows
