Struct ExecutionOptions 

Source 
pub struct ExecutionOptions {
    pub num_threads: Option<usize>,
    pub chunk_size: usize,
    pub max_in_flight_chunks: usize,
}
Expand description

Configuration for the ExecutionEngine.

Fields§

§num_threads: Option<usize>

Number of worker threads used by the engine.

If None, uses the platform’s available parallelism.

§chunk_size: usize

Number of rows per chunk.

Chunking lets the engine bound working-set size and implement throttling.

§max_in_flight_chunks: usize

Upper bound on concurrently executing chunks.

This is an additional throttle on top of num_threads.
