Excititor · Graph Indexes Prep (GRAPH-21-005)
- Date: 2025-11-20
- Depends on: GRAPH-21-002 overlays
- Working directory:
src/Excititor/__Libraries/StellaOps.Excititor.Storage.Mongo
Index plan
- Collection:
vex_observations- Compound index
{ tenant: 1, component.purl: 1, advisoryId: 1, source: 1, modifiedAt: -1 }(supports overlay queries and truncation cursor). - Sparse index
{ tenant: 1, component.purl: 1, status: 1 }for summary counts.
- Compound index
- Collection:
vex_overlays(materialized cache, optional)- Index
{ tenant: 1, purl: 1 }unique. - TTL index on
cachedAtconfigurable viaexcititor:graph:overlayTtlSeconds.
- Index
Determinism
- Materialization job must sort observations as per GRAPH-21-001 ordering before writing overlays so pagination/cursors align.
- TTL applied identically across tenants; default 300s, override allowed via config but must be documented.
Acceptance for prep completion
- Index keys and TTL knobs defined; downstream storage tasks can implement without further contract churn.
