Core Architectural Components

Log Ingestion & Parsing Agents

Ships raw log lines from every host/service into the pipeline.

Distributed Inverted Index

Enables fast full-text search across billions of log lines.

Field Extraction Pipeline

Parses structured fields out of semi-structured log text.

Hot/Warm/Cold Storage Tiering

Balances query speed against long-term storage cost.

Query Engine

Combines full-text search with structured field filters.

Alerting on Log Patterns

Fires on error-rate spikes or specific matched patterns.

Retention & Archival Policy Engine

Automatically ages data out of hot storage per compliance/cost rules.
