feat: plugin registry, list commands, and 5 tutorials#13
Merged
Conversation
Plugin Registry: - PluginLoader: scans ~/.weaver/plugins/ for external JARs at startup - InstallCommand: weaver install connector-kafka (Maven Central or local JAR) - ListCommand: weaver list connectors/transforms/plugins/all - Shorthands for official connectors (connector-kafka, connector-mongodb, etc.) Tutorials (5 complete pipelines with sample data): 1. CSV to Parquet: File I/O, SQL transforms, quality checks 2. Multi-source Join: parallel DAG, aggregation, JSON output 3. RAG Pipeline: document chunking for vector search 4. LLM Classification: Gemini/Ollama ticket classification 5. Production ETL: PostgreSQL → DeltaLake with connections, profiles, merge README updated with tutorials table, plugin registry docs, and new CLI commands.
Explains what META-INF/services files are, shows project structure, and clarifies that the file goes inside the connector project, not in Data Weaver itself.
