Enum mz_compute_client::response::ComputeResponse

pub enum ComputeResponse<T = Timestamp> {
    FrontierUppers(Vec<(GlobalId, Antichain<T>)>),
    PeekResponse(Uuid, PeekResponse, OpenTelemetryContext),
    SubscribeResponse(GlobalId, SubscribeResponse<T>),
}

Responses that the compute nature of a worker/dataflow can provide back to the coordinator.

Variants

FrontierUppers(Vec<(GlobalId, Antichain<T>)>)

A list of identifiers of traces, with new upper frontiers.

TODO(teskje): Consider also reporting the previous upper frontier and using that information to assert the correct implementation of our protocols at various places.

PeekResponse(Uuid, PeekResponse, OpenTelemetryContext)

The worker’s response to a specified (by connection id) peek.

SubscribeResponse(GlobalId, SubscribeResponse<T>)

The worker’s next response to a specified subscribe.

Trait Implementations

impl Arbitrary for ComputeResponse<Timestamp>

type Strategy = Union<BoxedStrategy<ComputeResponse<Timestamp>>>

The type of Strategy used to generate values of type Self.

type Parameters = ()

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

fn arbitrary_with(_: Self::Parameters) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl<T: Clone> Clone for ComputeResponse<T>

fn clone(&self) -> ComputeResponse<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: Debug> Debug for ComputeResponse<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de, T> Deserialize<'de> for ComputeResponse<T>where
    T: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T: Send> GenericClient<ComputeCommand<T>, ComputeResponse<T>> for Box<dyn ComputeClient<T>>

fn send<'life0, 'async_trait>(
    &'life0 mut self,
    cmd: ComputeCommand<T>
) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>where
    Self: 'async_trait,
    'life0: 'async_trait,

Sends a command to the dataflow server.

fn recv<'life0, 'async_trait>(
    &'life0 mut self
) -> Pin<Box<dyn Future<Output = Result<Option<ComputeResponse<T>>, Error>> + Send + 'async_trait>>where
    Self: 'async_trait,
    'life0: 'async_trait,

Receives the next response from the dataflow server.

fn as_stream<'a>(
    &'a mut self
) -> Pin<Box<dyn Stream<Item = Result<R, Error>> + Send + 'a, Global>>where
    R: 'a + Send,

Returns an adapter that treats the client as a stream.

impl<T: PartialEq> PartialEq<ComputeResponse<T>> for ComputeResponse<T>

fn eq(&self, other: &ComputeResponse<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T> Partitionable<ComputeCommand<T>, ComputeResponse<T>> for (ComputeCommand<T>, ComputeResponse<T>)where
    T: Timestamp + Lattice,

type PartitionedState = PartitionedComputeState<T>

The type which functions as the state machine for the partitioning.

fn new(parts: usize) -> PartitionedComputeState<T>

Construct a PartitionedState for the command–response pair.

impl<T> PartitionedState<ComputeCommand<T>, ComputeResponse<T>> for PartitionedComputeState<T>where
    T: Timestamp + Lattice,

fn split_command(
    &mut self,
    command: ComputeCommand<T>
) -> Vec<Option<ComputeCommand<T>>>

Splits a command into multiple partitions.

fn absorb_response(
    &mut self,
    shard_id: usize,
    message: ComputeResponse<T>
) -> Option<Result<ComputeResponse<T>, Error>>

Absorbs a response from a single partition.

impl RustType<ProtoComputeResponse> for ComputeResponse<Timestamp>

fn into_proto(&self) -> ProtoComputeResponse

Convert a Self into a Proto value.

fn from_proto(proto: ProtoComputeResponse) -> Result<Self, TryFromProtoError>

Consume and convert a Proto back into a Self value.

impl<T> Serialize for ComputeResponse<T>where
    T: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where
    __S: Serializer,

Serialize this value into the given Serde serializer.
