Expand description

Worker-local state related to the ingress or egress of collections of data.

Fields§

§source_uppers: BTreeMap<GlobalId, Rc<RefCell<Antichain<Timestamp>>>>

The highest observed upper frontier for collection.

This is shared among all source instances, so that they can jointly advance the frontier even as other instances are created and dropped. Ideally, the Storage module would eventually provide one source of truth on this rather than multiple, and we should aim for that but are not there yet.

§source_tokens: BTreeMap<GlobalId, Vec<PressOnDropButton>>

Handles to created sources, keyed by ID NB: The type of the tokens must not be changed to something other than PressOnDropButton to prevent usage of custom shutdown tokens that are tricky to get right.

§metrics: StorageMetrics

Metrics for storage objects.

§reported_frontiers: BTreeMap<GlobalId, Antichain<Timestamp>>

Tracks the conditional write frontiers we have reported.

§ingestions: BTreeMap<GlobalId, IngestionDescription<CollectionMetadata>>

Descriptions of each installed ingestion.

§exports: BTreeMap<GlobalId, StorageSinkDesc<MetadataFilled, Timestamp>>

Descriptions of each installed export.

§now: NowFn

Undocumented

§timely_worker_index: usize

Index of the associated timely dataflow worker.

§timely_worker_peers: usize

Peers in the associated timely dataflow worker.

§instance_context: StorageInstanceContext

Other configuration for sources and sinks.

§persist_clients: Arc<PersistClientCache>

A process-global cache of (blob_uri, consensus_uri) -> PersistClient. This is intentionally shared between workers

§sink_tokens: BTreeMap<GlobalId, Vec<PressOnDropButton>>

Tokens that should be dropped when a dataflow is dropped to clean up associated state. NB: The type of the tokens must not be changed to something other than PressOnDropButton to prevent usage of custom shutdown tokens that are tricky to get right.

§sink_write_frontiers: BTreeMap<GlobalId, Rc<RefCell<Antichain<Timestamp>>>>

Frontier of sink writes (all subsequent writes will be at times at or equal to this frontier)

§sink_handles: BTreeMap<GlobalId, SinkHandle>

See: SinkHandle

§dropped_ids: BTreeSet<GlobalId>

Collection ids that have been dropped but not yet reported as dropped

§aggregated_statistics: AggregatedStatistics

Statistics for sources and sinks.

§object_status_updates: Rc<RefCell<Vec<StatusUpdate>>>

Status updates reported by health operators.

NOTE: Operators that append to this collection should take care to only add new status updates if the status of the ingestion/export in question has changed.

§internal_cmd_tx: Rc<RefCell<dyn InternalCommandSender>>

Sender for cluster-internal storage commands. These can be sent from within workers/operators and will be distributed to all workers. For example, for shutting down an entire dataflow from within a operator/worker.

§async_worker: Rc<RefCell<AsyncStorageWorker<Timestamp>>>

Async worker companion, used for running code that requires async, which the timely main loop cannot do.

§storage_configuration: StorageConfiguration

Configuration for source and sink connections.

§dataflow_parameters: DataflowParameters

Dynamically configurable parameters that control how dataflows are rendered. NOTE(guswynn): we should consider moving these into storage_configuration.

§tracing_handle: Arc<TracingHandle>

A process-global handle to tracing configuration.

Implementations§

source§

impl StorageState

source

pub fn handle_storage_command( &mut self, worker_index: usize, internal_cmd_tx: &mut dyn InternalCommandSender, async_worker: &mut AsyncStorageWorker<Timestamp>, cmd: StorageCommand )

Entry point for applying a storage command.

NOTE: This does not have access to the timely worker and therefore cannot render dataflows. For dataflow rendering, this needs to either send asynchronous command to the given async_worker or internal commands to the given internal_cmd_tx.
