Struct VortexTableOptions 

pub struct VortexTableOptions {
    pub footer_initial_read_size_bytes: usize,
    pub projection_pushdown: bool,
    pub scan_concurrency: Option<usize>,
}

Options to configure the VortexFormat.

Can be set through a DataFusion SessionConfig.

Fields

footer_initial_read_size_bytes: usize

The number of bytes to read when parsing a file footer.

Values smaller than MAX_POSTSCRIPT_SIZE + EOF_SIZE will be clamped to that minimum during footer parsing.

projection_pushdown: bool

Whether to enable projection pushdown into the underlying Vortex scan.

When enabled, projection expressions may be partially evaluated during the scan. When disabled, Vortex reads only the referenced columns and all expressions are evaluated after the scan.

scan_concurrency: Option<usize>

The intra-partition scan concurrency, controlling the number of row splits to process concurrently per-thread within each file.

This does not affect the overall parallelism across partitions, which is controlled by DataFusion’s execution configuration.

Trait Implementations

impl Clone for VortexTableOptions

fn clone(&self) -> VortexTableOptions

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl ConfigField for VortexTableOptions

fn set(&mut self, key: &str, value: &str) -> Result<()>

fn visit<V: Visit>( &self, v: &mut V, key_prefix: &str, _description: &'static str, )

fn reset(&mut self, key: &str) -> Result<()>

impl Debug for VortexTableOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for VortexTableOptions

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for VortexTableOptions

fn eq(&self, other: &VortexTableOptions) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
