Required Methods§

Source

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

Initialize the sink committer coordinator.

Source

fn pre_commit<'life0, 'async_trait>( &'life0 mut self, epoch: u64, metadata: Vec<SinkMetadata>, add_columns: Option<Vec<Field>>, ) -> Pin<Box<dyn Future<Output = Result<Vec<u8>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Return serialized commit metadata to be passed to commit.

Source

fn commit<'life0, 'async_trait>( &'life0 mut self, epoch: u64, commit_metadata: Vec<u8>, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Idempotent implementation is required, because commit in the same epoch could be called multiple times.

Source

fn abort<'life0, 'async_trait>( &'life0 mut self, epoch: u64, commit_metadata: Vec<u8>, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Idempotent implementation is required, because abort in the same epoch could be called multiple times.
