[PR] feat(examples): add OpenSearch (#54) and All-Apache Lakehouse examples (flagon)
brucearctor opened a new pull request, #193:
URL: https://github.com/apache/flagon/pull/193
## Summary
Adds two 100% `Apache-2.0`-licensed backend deployment & analytics examples alongside the existing OpenTelemetry + Grafana/Loki/Tempo (`products/userale/example/otel-demo/`) and legacy ELK (`examples/elk/`) examples:
1. **OpenSearch Stack (`examples/opensearch/` — Closes #54)**:
- Docker Compose (`examples/opensearch/docker-compose.yml`) and Kubernetes (`examples/opensearch/kubernetes/opensearch.yaml`) configurations for **OpenTelemetry Collector + OpenSearch + OpenSearch Dashboards** (`Apache-2.0`).
- Includes an OpenSearch v2 index template (`examples/opensearch/userale-index-template.json`) mapping UserALE 2.5 telemetry (`targetRect`, `traceId`, `spanId`, and disabling `frames` indexing on `replay` envelopes to avoid segment bloat).
2. **All-Apache Behavioral Lakehouse (`examples/apache-lakehouse/`)**:
- Streaming lakehouse architecture using **Apache Flagon UserALE.js** (`OtlpJsonExporter`) $\rightarrow$ **OpenTelemetry Collector** $\rightarrow$ **Apache Kafka** (`apache/kafka-native` KRaft) $\rightarrow$ **Apache Iceberg / Apache Parquet / Apache Arrow** $\rightarrow$ **Apache DataFusion** + **Apache Flagon Distill 2.5**.
- Includes a self-contained, runnable Python script (`examples/apache-lakehouse/distill_lakehouse_demo.py`) that normalizes OTLP/JSON logs via Distill, writes an Apache Parquet dataset, runs vectorized SQL window functions (`LEAD()` over session partitions) via **Apache DataFusion**, and computes UX frustration scores, Markov transition matrices, and W3C trace correlations via **Distill 2.5**.
3. **Top-Level Examples Index (`examples/README.md`)**:
- Compares all four supported deployment architectures (`OpenTelemetry + Grafana/Loki/Tempo`, `All-Apache Behavioral Lakehouse`, `OpenSearch`, and legacy `ELK`).
Closes #54
