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).

§

VectorCoarseRoute

Compass coarse-route handler: shard returns its coarse routing descriptor.

§

VectorBuildExchange

SPIRE build-time exchange: shard sends or receives IVF centroid tables.

§

VectorMemRegion

CoTra-RDMA memory region handler: shard registers or exposes a pinned memory region for one-sided reads by a remote peer.

§

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).

§

ArrayShard

Array shard: executes slice/agg/put/delete/surrogate-scan locally.

§

ArrayCoordinator

Array coordinator: receives shard responses and merges them.
