ThemisDB Analytics Module

Module Purpose

The analytics module provides analytical runtime capabilities for OLAP execution, streaming analytics, CEP, forecasting, anomaly detection, process mining, ML serving, and analytics export paths.

Relevant Interfaces

Interface / File Role
olap.cpp OLAP query execution and aggregation paths
cep_engine.cpp event pattern processing and rule execution
streaming_window.cpp tumbling, sliding, session, and hopping windows
streaming_join.cpp stream join execution paths
forecasting.cpp time-series fit/predict/evaluate flows
anomaly_detection.cpp statistical and model-based anomaly scoring
model_serving.cpp in-process model registry and inference
ml_serving.cpp external model serving integration
analytics_export.cpp analytics export orchestration
arrow_export.cpp columnar export conversion paths
distributed_analytics.cpp shard fan-out and aggregation coordination

Scope

In scope:

  • OLAP and analytics runtime execution surfaces
  • streaming and CEP processing paths
  • forecasting, anomaly detection, and model serving integration
  • analytics export and distributed analytics coordination

Out of scope:

  • raw query language parsing
  • model lifecycle ownership outside analytics integration boundaries
  • storage engine internals beyond consumed interfaces

Runtime Behavior and Limits

  • runtime behavior depends on feature flags and available optional dependencies.
  • analytics execution paths include both local and distributed orchestration surfaces.
  • export and serving integrations can return structured not-supported or dependency errors when optional backends are unavailable.

Sourcecode Verification (Module: analytics/readme)

  • Verified files:
    • src/analytics/olap.cpp
    • src/analytics/cep_engine.cpp
    • src/analytics/streaming_window.cpp
    • src/analytics/streaming_join.cpp
    • src/analytics/forecasting.cpp
    • src/analytics/anomaly_detection.cpp
    • src/analytics/model_serving.cpp
    • src/analytics/ml_serving.cpp
    • src/analytics/analytics_export.cpp
    • src/analytics/arrow_export.cpp
    • src/analytics/distributed_analytics.cpp
  • Verified behavior surfaces:
    • analytical execution and streaming paths
    • forecasting/anomaly/model-serving integration paths
    • export and distributed orchestration surfaces
  • Note:
    • forward planning is tracked in ROADMAP.md and FUTURE_ENHANCEMENTS.md
    • historical completion remains in CHANGELOG.md
