|
## Status

|
|
## Description
|
|
Graph analytics with engine, pipeline, DI extensions, and Postgres persistence for analytics results.
|
|
|
|
## Implementation Details
|
|
- **Analytics engine**: `src/Graph/StellaOps.Graph.Indexer/Analytics/GraphAnalyticsEngine.cs` -- core graph analytics computation engine
|
|
- **Analytics pipeline**: `src/Graph/StellaOps.Graph.Indexer/Analytics/GraphAnalyticsPipeline.cs` -- multi-stage analytics pipeline orchestration
|
|
- **Hosted service**: `src/Graph/StellaOps.Graph.Indexer/Analytics/GraphAnalyticsHostedService.cs` -- background service running analytics on schedule
|
|
- **Analytics types**: `src/Graph/StellaOps.Graph.Indexer/Analytics/GraphAnalyticsTypes.cs` -- clustering, centrality, and analytics result types
|
|
- **Metrics**: `src/Graph/StellaOps.Graph.Indexer/Analytics/GraphAnalyticsMetrics.cs` -- Prometheus-compatible analytics execution metrics
|
|
- **Options**: `src/Graph/StellaOps.Graph.Indexer/Analytics/GraphAnalyticsOptions.cs` -- configurable analytics parameters
|
|
- **Writer options**: `src/Graph/StellaOps.Graph.Indexer/Analytics/GraphAnalyticsWriterOptions.cs` -- result persistence configuration
|
|
- **Overlay exporter**: `src/Graph/StellaOps.Graph.Indexer/Analytics/GraphOverlayExporter.cs` -- exports analytics results as graph overlays
|
|
- **In-memory writer**: `src/Graph/StellaOps.Graph.Indexer/Analytics/InMemoryGraphAnalyticsWriter.cs` -- test analytics writer
|
|
- **In-memory snapshot**: `src/Graph/StellaOps.Graph.Indexer/Analytics/InMemoryGraphSnapshotProvider.cs` -- test snapshot provider
|
|
- **DI extensions**: `src/Graph/StellaOps.Graph.Indexer/Analytics/GraphAnalyticsServiceCollectionExtensions.cs` -- DI registration
|
|
- **Postgres persistence**: `src/Graph/__Libraries/StellaOps.Graph.Indexer.Persistence/Postgres/Repositories/PostgresGraphAnalyticsWriter.cs` -- PostgreSQL analytics result storage
|
|
- **Tests**: `src/Graph/__Tests/StellaOps.Graph.Indexer.Tests/GraphAnalyticsEngineTests.cs`, `GraphAnalyticsPipelineTests.cs`, `GraphOverlayExporterTests.cs`, `GraphAnalyticsTestData.cs`
|
|
- **Source**: Feature matrix scan
|
|
|
|
