Architecture - Analytics Module

Overview

The analytics module is a multi-surface runtime for analytical workloads. It combines OLAP execution, streaming/CEP processing, forecasting, anomaly detection, and model-serving integrations behind shared analytics interfaces.

Main Execution Planes

  1. OLAP and aggregation plane
  • group-by and analytical aggregation execution
  • columnar and export-related execution paths
  1. Streaming and CEP plane
  • windowed streaming computation
  • pattern detection and rule-driven CEP processing
  • stream join coordination
  1. Predictive and ML integration plane
  • forecasting and anomaly scoring
  • in-process and external model-serving integration
  1. Distributed orchestration plane
  • shard fan-out execution
  • partial-result aggregation and coordination

Core Contracts

Contract Behavior
analytics execution APIs perform analytical computations and result shaping
streaming/CEP APIs evaluate windows and event patterns
forecasting/anomaly APIs provide predictive and outlier analysis flows
model serving APIs connect analytics requests to model inference paths
distributed analytics APIs coordinate multi-shard execution and result merge

Failure Semantics

  • optional-backend paths fail with structured errors when capabilities are unavailable.
  • runtime execution paths preserve fail-closed behavior on invalid inputs or unsupported operations.
  • distributed analytics paths can return partial outcomes according to module policy.

Sourcecode Verification (Module: analytics/architecture)

  • Verified implementation files:
    • src/analytics/olap.cpp
    • src/analytics/streaming_window.cpp
    • src/analytics/streaming_join.cpp
    • src/analytics/cep_engine.cpp
    • src/analytics/forecasting.cpp
    • src/analytics/model_serving.cpp
    • src/analytics/distributed_analytics.cpp
  • Verified architecture claims:
    • multi-plane analytics runtime composition
    • optional dependency and capability-sensitive execution paths
    • distributed coordination present in dedicated implementation file
