Struct IngestionClient Copy item path

impl IngestionClient

pub fn new( args: IngestionClientArgs, metrics: Arc<IngestionMetrics>, ) -> IngestionResult<Self>

Construct a new ingestion client. Its source is determined by args.

pub fn new_remote( url: Url, metrics: Arc<IngestionMetrics>, ) -> IngestionResult<Self>

An ingestion client that fetches checkpoints from a remote store (an object store, over HTTP).

pub fn new_remote_with_timeout( url: Url, timeout: Duration, metrics: Arc<IngestionMetrics>, ) -> IngestionResult<Self>

An ingestion client that fetches checkpoints from a remote store (an object store, over HTTP), with a configured request timeout.

pub fn new_local(path: PathBuf, metrics: Arc<IngestionMetrics>) -> Self

An ingestion client that fetches checkpoints from a local directory.

pub fn new_rpc( url: Url, username: Option<String>, password: Option<String>, metrics: Arc<IngestionMetrics>, ) -> IngestionResult<Self>

An ingestion client that fetches checkpoints from a fullnode, over gRPC.

pub async fn wait_for( &self, checkpoint: u64, retry_interval: Duration, ) -> IngestionResult<Arc<Checkpoint>>

Fetch checkpoint data by sequence number.

This function behaves like IngestionClient::fetch, but will repeatedly retry the fetch if the checkpoint is not found, on a constant back-off. The time between fetches is controlled by the retry_interval parameter.

pub async fn fetch(&self, checkpoint: u64) -> IngestionResult<Arc<Checkpoint>>

Fetch checkpoint data by sequence number.

Repeatedly retries transient errors with an exponential backoff (up to MAX_TRANSIENT_RETRY_INTERVAL). Transient errors are either defined by the client implementation that returns a FetchError::Transient error variant, or within this function if we fail to deserialize the result as Checkpoint.

The function will immediately return if the checkpoint is not found.
