Struct DiskManagerBuilder 

pub struct DiskManagerBuilder { /* private fields */ }

Builder pattern for the DiskManager structure

Implementations

impl DiskManagerBuilder

pub fn set_mode(&mut self, mode: DiskManagerMode)

pub fn with_mode(self, mode: DiskManagerMode) -> Self

pub fn set_temp_file_factory( &mut self, temp_file_factory: Arc<dyn TempFileFactory>, )

Configure a custom factory for creating temporary spill files.

This sets the disk manager mode to DiskManagerMode::Custom, so operators that spill during query execution create files through the provided TempFileFactory instead of using local temporary files.

pub fn with_temp_file_factory( self, temp_file_factory: Arc<dyn TempFileFactory>, ) -> Self

Configure a custom factory for creating temporary spill files.

See details on Self::set_temp_file_factory.

pub fn set_max_temp_directory_size(&mut self, value: u64)

pub fn with_max_temp_directory_size(self, value: u64) -> Self

pub fn set_max_spill_merge_fan_in(&mut self, value: usize)

pub fn with_max_spill_merge_fan_in(self, value: usize) -> Self

pub fn build(self) -> Result<DiskManager>

Create a DiskManager given the builder
