Struct BatchUploadWriter

pub struct BatchUploadWriter {
    object_id: HummockSstableObjectId,
    sstable_store: SstableStoreRef,
    policy: CachePolicy,
    buf: Vec<u8>,
    block_info: Vec<Block>,
    tracker: Option<MemoryTracker>,
}

Buffer SST data and upload it as a whole on finish. The upload is finished when the returned JoinHandle is joined.

Fields

object_id: HummockSstableObjectId

sstable_store: SstableStoreRef

policy: CachePolicy

buf: Vec<u8>

block_info: Vec<Block>

tracker: Option<MemoryTracker>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Write an SST block to the writer.

fn write_block_bytes<'life0, 'life1, 'async_trait>( &'life0 mut self, block: Bytes, meta: &'life1 BlockMeta, ) -> Pin<Box<dyn Future<Output = HummockResult<()>> + Send + 'async_trait>>

fn finish<'async_trait>( self, meta: SstableMeta, ) -> Pin<Box<dyn Future<Output = HummockResult<Self::Output>> + Send + 'async_trait>>

where Self: 'async_trait,

Finish writing the SST.

fn data_len(&self) -> usize

Get the length of data that has already been written.
