Struct lance_io::scheduler::ScanScheduler

source ·

pub struct ScanScheduler { /* private fields */ }

Expand description

An I/O scheduler which wraps an ObjectStore and throttles the amount of parallel I/O that can be run.

TODO: This will also add coalescing

Implementations§

source §

impl ScanScheduler

source

pub fn new(object_store: Arc<ObjectStore>, io_capacity: u32) -> Arc<Self>

object_store - the store to wrap
io_capacity - the maximum number of parallel requests that will be allowed

source

pub async fn open_file(self: &Arc<Self>, path: &Path) -> Result<FileScheduler>
