}

Fields

actor_dispatchers: HashMap<ActorId, Dispatchers>

New dispatchers for each actor.

added_actors: Vec<ActorId>

All actors to be added (to the main connected component of the graph) in this update.

actor_splits: HashMap<ActorId, ConnectorSplits>

We may embed a source change split mutation here. Source and SourceBackfill are handled together here. TODO: we may allow multiple mutations in a single barrier.

pause: bool

We may embed a pause mutation here. TODO: we may allow multiple mutations in a single barrier.

subscriptions_to_add: Vec<SubscriptionUpstreamInfo>

backfill_nodes_to_pause: Vec<FragmentId>

nodes which should be paused initially.

actor_cdc_table_snapshot_splits: Option<CdcTableSnapshotSplitsWithGeneration>

CDC table snapshot splits

new_upstream_sinks: HashMap<FragmentId, NewUpstreamSink>

Use downstream_fragment_id as keys.

Trait Implementations

impl Clone for AddMutation

fn clone(&self) -> AddMutation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AddMutation

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

Formats the value using the given formatter.

impl Default for AddMutation

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AddMutation

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for AddMutation

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for AddMutation

fn eq(&self, other: &AddMutation) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for AddMutation

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
