Architecture
XplurData runs as four Docker containers working together: the OpenTelemetry Collector ingests telemetry over OTLP/HTTP, Apache Doris (Frontend + Backend) stores and indexes it, and the Application serves the web UI for search and exploration.
Databases
| Database | Tables | Purpose |
|---|---|---|
otel_db | otel_logs, otel_traces, otel_metrics | Live telemetry from the OTel Collector |
demo_otel_db | otel_logs | Pre-seeded demo data (10,000 records) |
The four containers
| Container | Role |
|---|---|
| OTel Collector | Receives logs via OTLP/HTTP on port 4318 and forwards them to Doris |
| Doris Frontend (FE) | Query coordination, metadata, SQL endpoint |
| Doris Backend (BE) | Columnar storage and query execution |
| Application | Web UI (port 80) for full-text search, filtering, and real-time querying |
