Expand description
A wrapper around ComputeState with a live timely worker and response channel.
Fields§
§timely_worker: &'a mut Worker<A>
The underlying Timely worker.
compute_state: &'a mut ComputeState
The compute state itself.
response_tx: &'a mut ResponseSender
The channel over which frontier information is reported.
Implementations§

impl<'a, A: Allocate + 'static> ActiveComputeState<'a, A>
sourcepub fn handle_compute_command(&mut self, cmd: ComputeCommand)
pub fn handle_compute_command(&mut self, cmd: ComputeCommand)
Entrypoint for applying a compute command.
fn handle_create_instance(&mut self, config: InstanceConfig)
fn handle_update_configuration(&mut self, params: ComputeParameters)
fn handle_create_dataflow( &mut self, dataflow: DataflowDescription<Plan, CollectionMetadata> )
fn handle_allow_compaction( &mut self, id: GlobalId, frontier: Antichain<Timestamp> )
fn handle_peek(&mut self, peek: Peek)
fn handle_cancel_peek(&mut self, uuid: Uuid)
fn drop_collection(&mut self, id: GlobalId)
sourcepub fn initialize_logging(&mut self, config: &LoggingConfig)
pub fn initialize_logging(&mut self, config: &LoggingConfig)
Initializes timely dataflow logging and publishes as a view.
sourcepub fn report_compute_frontiers(&mut self)
pub fn report_compute_frontiers(&mut self)
Send progress information to the coordinator.
sourcepub fn report_dropped_collections(&mut self)
pub fn report_dropped_collections(&mut self)
Report dropped collections to the controller.
sourcepub fn report_operator_hydration(&mut self)
pub fn report_operator_hydration(&mut self)
Report operator hydration events.
sourcefn process_peek(&mut self, upper: &mut Antichain<Timestamp>, peek: PendingPeek)
fn process_peek(&mut self, upper: &mut Antichain<Timestamp>, peek: PendingPeek)
Either complete the peek (and send the response) or put it in the pending set.
sourcepub fn process_peeks(&mut self)
pub fn process_peeks(&mut self)
Scan pending peeks and attempt to retire each.
sourcefn send_peek_response(&mut self, peek: PendingPeek, response: PeekResponse)
fn send_peek_response(&mut self, peek: PendingPeek, response: PeekResponse)
Sends a response for this peek’s resolution to the coordinator.
Note that this function takes ownership of the PendingPeek
, which is
meant to prevent multiple responses to the same peek.
sourcepub fn process_subscribes(&mut self)
pub fn process_subscribes(&mut self)
Scan the shared subscribe response buffer, and forward results along.
sourcepub fn process_copy_tos(&mut self)
pub fn process_copy_tos(&mut self)
Scan the shared copy to response buffer, and forward results along.
sourcefn send_compute_response(&self, response: ComputeResponse)
fn send_compute_response(&self, response: ComputeResponse)
Send a response to the coordinator.
