Implementations

impl StarrocksSinkWriter

pub fn new( config: StarrocksConfig, schema: Schema, pk_indices: Vec<usize>, is_append_only: bool, executor_id: u64, ) -> Result<Self>

async fn append_only(&mut self, chunk: StreamChunk) -> Result<()>

async fn upsert(&mut self, chunk: StreamChunk) -> Result<()>

fn new_txn_label(&self) -> String

Generating a new transaction label, should be unique across all SinkWriters even under rewinding.

Trait Implementations

impl Drop for StarrocksSinkWriter

fn drop(&mut self)

Executes the destructor for this type.

impl SinkWriter for StarrocksSinkWriter

type CommitMetadata = Option<SinkMetadata>

fn begin_epoch<'life0, 'async_trait>( &'life0 mut self, _epoch: u64, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Begin a new epoch

fn write_batch<'life0, 'async_trait>( &'life0 mut self, chunk: StreamChunk, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Write a stream chunk to sink

fn barrier<'life0, 'async_trait>( &'life0 mut self, is_checkpoint: bool, ) -> Pin<Box<dyn Future<Output = Result<Option<SinkMetadata>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Receive a barrier and mark the end of current epoch. When is_checkpoint is true, the sink writer should commit the current epoch.

fn abort<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Clean up

fn update_vnode_bitmap<'life0, 'async_trait>( &'life0 mut self, _vnode_bitmap: Arc<Bitmap>, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Update the vnode bitmap of current sink writer
