Message types for vShard wire protocol.

Variants

SegmentChunk = 1

Phase 1: Segment file chunk during base copy.

SegmentComplete = 2

Phase 1: Segment transfer complete marker.

WalTail = 3

Phase 2: WAL tail entries for catch-up.

RoutingUpdate = 4

Phase 3: Routing table update (atomic cut-over).

RoutingAck = 5

Routing table acknowledgement.

GhostCreate = 10

Ghost stub creation notification.

GhostDelete = 11

Ghost stub deletion notification.

GhostVerifyRequest = 12

Anti-entropy sweep query.

GhostVerifyResponse = 13

Anti-entropy sweep response.

MigrationBaseCopy = 20

CrossShardForward = 21

Cross-shard transaction forward.

GsiForward = 22

EdgeValidation = 23

Edge validation request.

GraphAlgoSuperstep = 30

Superstep barrier: coordinator tells all shards to begin iteration N.

GraphAlgoContributions = 31

Boundary vertex contributions: shard sends rank contributions for vertices owned by the target shard (scatter phase).

GraphAlgoSuperstepAck = 32

Superstep complete: shard reports local convergence delta and vertex count to coordinator (gather phase).

GraphAlgoComplete = 33

Algorithm complete: coordinator broadcasts final signal with global convergence status.

TsScatterRequest = 40

Scatter: coordinator sends aggregation query to a shard.

TsScatterResponse = 41

Gather: shard responds with partial aggregates.

TsRetentionCommand = 42

Coordinator broadcasts retention command to all shards.

TsRetentionAck = 43

Shard acknowledges retention execution.

TsArchiveCommand = 44

S3 archival command: coordinator tells shard to archive partitions.

TsArchiveAck = 45

S3 archival acknowledgement.

VectorScatterRequest = 50

Scatter: coordinator sends k-NN query to a shard.

VectorScatterResponse = 51

Gather: shard responds with local top-K hits.

SpatialScatterRequest = 60

Scatter: coordinator sends spatial predicate query to a shard.

SpatialScatterResponse = 61

Gather: shard responds with matching document IDs.

CrossShardEvent = 70

Cross-shard event write request (trigger DML, CDC, etc.).

CrossShardEventAck = 71

Acknowledgement for a cross-shard event write.

NotifyBroadcast = 72

Broadcast NOTIFY message to all peers (LISTEN/NOTIFY cluster-wide).

NotifyBroadcastAck = 73

Acknowledgement for a NOTIFY broadcast.

Trait Implementations

impl Clone for VShardMessageType

fn clone(&self) -> VShardMessageType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VShardMessageType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VShardMessageType

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for VShardMessageType

fn eq(&self, other: &VShardMessageType) -> 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 VShardMessageType

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
