It provides the foundational set of data processing nodes used in most workflows.\n\n---\n\n## 🔥 What Is This\n\nA standalone Gradle project containing **16 production-ready workflow nodes** for data transformation, filtering, aggregation, REST integration, scripting, and anomaly detection. Ships as a Spring Boot worker that registers all nodes with Temporal for durable execution.\n\n---\n\n## 🧩 Included Nodes\n\n| Category | Node | Description |\n|----------|------|-------------|\n| **Data** | Create Table | Creates a structured table from FreeMarker template configuration |\n| **Data** | Column Join | Joins two columns from left and right tables into one output column |\n| **Data** | Joint Node | Joins input strings into one |\n| **Data** | Join on Multiple Keys | Performs inner join on two tables using two key columns from each table |\n| **Transform** | Pivot Columns | Pivots table so pivot column values become new columns with value column as cell values |\n| **Transform** | JSON Exploder | Parses JSON strings and flattens keys into new columns |\n| **Transform** | Column Splitter | Splits a column into two parts |\n| **Transform** | Kotlin Script | Runs a Kotlin script for each row, adding a script_result column |\n| **Filter** | Dynamic Row Filter | Filters rows where the specified column value is greater than the threshold |\n| **Filter** | Conditional Splitter | Splits rows into two outputs based on threshold comparison |\n| **Aggregation** | Time Window Aggregator | Aggregates values into time windows, summing by window buckets |\n| **Aggregation** | Batch Accumulator | Groups rows into batches and adds batch_id and row_count columns |\n| **Text** | Text Normalizer | Normalizes text by trimming, lowercasing, and removing non-alphanumeric characters |\n| **Security** | Crypto Hasher | Generates SHA-256 hash of column values |\n| **Analytics** | Anomaly Detector (Z-Score) | Detects outliers using Z-score method (flags values with \\|Z\\| \u003e 2) |\n| **Integration** | REST Client | Makes HTTP requests for each row using FreeMarker templated URLs and payloads |\n\n---\n\n## 📦 Dependencies\n\nThis worker depends on shared libraries published from the [Continuum](https://github.com/projectcontinuum/Continuum) monorepo via GitHub Packages:\n\n| Dependency | Purpose |\n|-----------|---------|\n| `continuum-commons:0.0.1` | Base node model, data types, Parquet/S3 utilities |\n| `continuum-avro-schemas:0.0.1` | Shared Kafka message schemas |\n| `continuum-worker-springboot-starter:0.0.1` | Worker framework — registers nodes with Temporal |\n\nAdditional infrastructure libraries: Kafka + Confluent Avro, Temporal SDK, AWS SDK (S3), MQTT Paho, FreeMarker, Kotlin Scripting.\n\n---\n\n## 🚀 Quick Start\n\n### Prerequisites\n\n- **JDK 21** — [Eclipse Temurin](https://adoptium.net/) recommended\n- **Docker \u0026 Docker Compose** — For local infrastructure\n- **GitHub PAT** with `read:packages` scope\n\nSet environment variables:\n\n```bash\nexport GITHUB_USERNAME=your-github-username\nexport GITHUB_TOKEN=ghp_your-personal-access-token\n```\n\n### Run\n\n```bash\n# Start infrastructure (Temporal, Kafka, MinIO, API Server, Message Bridge)\ncd docker \u0026\u0026 docker compose up -d\n\n# Build\n./gradlew build\n\n# Start the base analytics worker\n./gradlew :worker:bootRun\n```\n\nYour worker is now running and all 16 nodes are registered with Temporal.\n\n---\n\n## 📁 Project Structure\n\n```\ncontinuum-feature-base/\n├── features/\n│   └── continuum-feature-analytics/          #
