+# Apache Flagon Deployment & Analytics Examples
+
+Apache Flagon UserALE.js and Distill support multiple open-standard wire formats (`userale-json`, `otlp-json`, and `proto-json`), allowing you to choose the right backend architecture for your workload:
+
+| Example | Stack & License | Best For |
+| :--- | :--- | :--- |
+| **[OpenTelemetry + Grafana/Loki/Tempo](../products/userale/example/otel-demo/README.md)** | `OtlpJsonExporter` $\rightarrow$ OTel Collector $\rightarrow$ Loki + Tempo + Grafana | **SRE & Observability Teams**: Correlating frontend user interactions, rage-clicks, and errors with distributed backend traces (`traceId` / `spanId`). |
+| **[All-Apache Behavioral Lakehouse](./apache-lakehouse/README.md)** | `OtlpJsonExporter` $\rightarrow$ OTel Collector $\rightarrow$ **Apache Kafka** $\rightarrow$ **Apache Iceberg / Parquet** $\rightarrow$ **Apache DataFusion** + **Apache Flagon Distill** (`100% Apache-2.0`) | **Product Analytics & Data Science at Scale**: Columnar storage without inverted-index bloat, fast SQL window functions (`LEAD`/`LAG` funnels), and zero-copy Python analytics with Distill. |
+| **[OpenSearch Stack](./opensearch/README.md)** | `OtlpJsonExporter` $\rightarrow$ OTel Collector $\rightarrow$ **OpenSearch** + **OpenSearch Dashboards** (`100% Apache-2.0`) | **Search & Log Indexing**: Drop-in `Apache-2.0` open-source replacement for the legacy ELK stack (Docker Compose + Kubernetes). |
+| **[Legacy ELK Stack](./elk/docker/README.md)** | UserALE JSON $\rightarrow$ Logstash $\rightarrow$ Elasticsearch + Kibana | Legacy compatibility for existing Elasticsearch deployments. |

+# The "All-Apache" Behavioral Lakehouse Example
+
+**Apache Flagon UserALE.js + Apache Kafka + Apache Iceberg + Apache DataFusion + Apache Flagon Distill + Apache Superset**
+
+This directory demonstrates a modern, **100% Apache Software Foundation (`Apache-2.0`)** streaming lakehouse and behavioral OLAP architecture for high-volume frontend telemetry.
+
+---
+
+## Why a Behavioral Lakehouse Instead of Legacy ELK?
+
+1. **Zero Inverted-Index Amplification**: High-frequency UserALE interaction streams (`mousemove`/`scroll` intervals, `click` coordinates, `mutation` summaries, and `rrweb` session replay envelopes) are stored in columnar **Apache Parquet / Apache Iceberg** tables rather than expensive JVM heap and Lucene inverted indexes.
+2. **Native SQL Window Functions for Funnels & Sequences**: Vectorized engines like **Apache DataFusion** (and **Apache Pinot** / **DuckDB**) execute ordered session window queries (`LEAD()`, `LAG()`, `OVER (PARTITION BY session_id ORDER BY client_time)`) in milliseconds.
+3. **Zero-Copy Python Analytics with Apache Flagon Distill**: **Distill** reads Arrow/Parquet/Iceberg partitions directly into Python to compute UX frustration scores (`distill.frustration_score`), Markov transition matrices (`distill.transition_matrix`), spatial click heatmaps (`distill.click_heatmap_data`), and OpenTelemetry trace correlations (`distill.correlate_by_trace`).
+4. **100% ASF Category-A Open Source**: Every component in this stack is governed by the Apache Software Foundation (or CNCF) under the permissive **Apache-2.0** license—no BSL 1.1 or AGPLv3 dependencies.
+
+---
+
+## Architecture
+
+```
+Browser (Apache Flagon UserALE.js — OtlpJsonExporter / ProtoJsonExporter)
+ │ POST http://localhost:4318/v1/logs (OTLP/JSON + W3C traceId/spanId)
+ ▼

+ ├──► Apache Kafka (apache/kafka-native KRaft, Apache-2.0)

+ └──► Apache Superset (Interactive BI Dashboards)
+```
+
+---
+
+## Quickstart
+
+### 1. Run the Self-Contained Distill + Arrow/DataFusion Lakehouse Demo Script
+
+You can run the end-to-end Python lakehouse & behavioral analytics pipeline immediately using `uv` inside the repository's Nix development shell:
+
+```bash
+nix develop -c uv run --no-project \
+ --with networkx --with pandas --with plotly --with pydantic \
+ --with dateparser --with pksuid --with pyarrow --with datafusion \
+ python examples/apache-lakehouse/distill_lakehouse_demo.py
+```
+
+This script:
+1. Normalizes a realistic **UserALE 2.5 OTLP/JSON** batch (containing `click`, `rage_click`, `mutation`, `scroll`, and `session_replay` events correlated with W3C `traceId`/`spanId` and `targetRect` geometry) via `distill.schemas.userale.extract_logs`.
+2. Writes the normalized batch to an **Apache Arrow / Apache Parquet** lakehouse table (and demonstrates registering an **Apache Iceberg** table via `pyiceberg`).
+3. Queries the table using **Apache DataFusion SQL** (`OVER (PARTITION BY session_id ORDER BY client_time)` window functions) to compute next-target transitions and per-page friction metrics.
+4. Runs **Apache Flagon Distill 2.5** analytics (`session_summary`, `frustration_score`, `detect_rage_clicks`, `detect_dead_clicks`, `detect_dom_thrash`, `transition_matrix`, and `correlate_by_trace`).
+
+---
+
+### 2. Start the Streaming Docker Compose Stack (OTel Collector + Apache Kafka + Apache Iceberg REST Catalog)
+
+```bash
+docker compose -f examples/apache-lakehouse/docker-compose.yml up -d
+```
+
+- **OTLP HTTP Endpoint**: `http://localhost:4318/v1/logs` (CORS enabled for browser `fetch` / `keepalive`)
+- **Apache Kafka Broker (KRaft)**: `localhost:9092` (topic: `flagon-userale-events`)
+- **Apache Iceberg REST Catalog**: `http://localhost:8181`
+
+To stop and clean up:
+
+```bash
+docker compose -f examples/apache-lakehouse/docker-compose.yml down -v
+```

+OpenSearch Dashboards (:5601, Apache-2.0)
+```
+
+---
+
+## 1. Docker Compose Quickstart
+
+### Step 1: Start OpenSearch, OpenSearch Dashboards, and the OpenTelemetry Collector
+
+```bash
+docker compose -f examples/opensearch/docker-compose.yml up -d
+```
+
+### Step 2: Apply the UserALE Index Template (Optional, Recommended for Flat JSON Ingest)
+
+```bash
+curl -X PUT "http://localhost:9200/_index_template/flagon-userale" \
+ -H "Content-Type: application/json" \
+ -d @examples/opensearch/userale-index-template.json
+```
+
+### Step 3: Send Telemetry from UserALE.js
+
+Configure UserALE.js in your application (or open `products/userale/example/otel-demo/index.html`) to export OTLP/JSON to `http://localhost:4318/v1/logs`:
+
+```javascript
+import * as userale from "flagon-userale";
+
+userale.options({
+ url: "http://localhost:4318/v1/logs",
+ exporterFormat: "otlp-json",
+ toolName: "my-web-app",
+ toolVersion: "1.0.0",
+ observeMutations: true,
+ detectRageClicks: true,
+});
+```
+
+### Step 4: Explore in OpenSearch Dashboards
+
+1. Open [http://localhost:5601](http://localhost:5601).
+2. Go to **Stack Management -> Index Patterns** and create an index pattern matching `flagon-userale*` using `@timestamp` (or `clientTime` for direct JSON ingestion) as the time field.
+3. Open **Discover** to query clicks, rage-clicks (`attributes.flagon.event_type: "rage_click"`), DOM mutations (`attributes.flagon.log_type: "mutation"`), and correlated `traceId` spans.
+
+### Step 5: Tear Down
+
+```bash
+docker compose -f examples/opensearch/docker-compose.yml down -v
+```
+
+---
+
+## 2. Kubernetes Deployment
+
+To deploy the OpenTelemetry Collector + OpenSearch + OpenSearch Dashboards stack in a Kubernetes cluster (such as `kind`, `minikube`, or an enterprise cluster):
+
+```bash
+kubectl apply -f examples/opensearch/kubernetes/opensearch.yaml
+kubectl -n flagon-opensearch port-forward svc/otel-collector 4318:4318 &
+kubectl -n flagon-opensearch port-forward svc/opensearch-dashboards 5601:5601 &
+```
