Implementations§

Source§

impl CheckpointService

Source

pub fn build( state: Arc<AuthorityState>, checkpoint_store: Arc<CheckpointStore>, epoch_store: Arc<AuthorityPerEpochStore>, effects_store: Arc<dyn TransactionCacheRead>, accumulator: Weak<StateAccumulator>, checkpoint_output: Box<dyn CheckpointOutput>, certified_checkpoint_output: Box<dyn CertifiedCheckpointOutput>, metrics: Arc<CheckpointMetrics>, max_transactions_per_checkpoint: usize, max_checkpoint_size_bytes: usize, ) -> Arc<Self>

Constructs a new CheckpointService in an un-started state.

Source

pub async fn spawn(&self) -> JoinSet<()>

Starts the CheckpointService.

This function blocks until the CheckpointBuilder re-builds all checkpoints that had been built before the most recent restart. You can think of this as a WAL replay operation. Upon startup, we may have a number of consensus commits and resulting checkpoints that were built but not committed to disk. We want to reprocess the commits and rebuild the checkpoints before starting normal operation.

impl CheckpointService

Source

pub async fn wait_for_rebuilt_checkpoints(&self)

Waits until all checkpoints had been built before the node restarted are rebuilt.
