Expand description

Which engine subsystem should handle this envelope.

Variants§

GraphBsp

Graph BSP algorithm handler.

GraphValidation

Graph edge validation.

TimeseriesScan

Timeseries local scan (shard executes scan, returns partials).

TimeseriesCoordinator

Timeseries coordinator (receives shard responses).

TimeseriesRetention

Timeseries retention enforcement on local shard.

TimeseriesArchive

Timeseries S3 archive execution on local shard.

VectorSearch

Vector local k-NN search (shard executes search, returns top-K hits).

VectorCoordinator

Vector coordinator (receives shard search responses).

Migration

Migration infrastructure.

Ghost

Ghost stub management.

Forward

Query/transaction forwarding.

SpatialSearch

Spatial local R-tree search (shard executes predicate, returns matching docs).

SpatialCoordinator

Spatial coordinator (receives shard search responses).

EventPlane

Event Plane cross-shard delivery (trigger DML, CDC events).

Trait Implementations§

impl Clone for DispatchTarget
