AI Analysis

●●SolidNiche GemShip It

DuckDB-inspired embedded pipelines for JVM when Flink is overkill.

Strengths
  • •Chunked execution with serial checkpointing enables resumable pipelines without a broker.
  • •Spring Boot starter and SmartLifecycle adapter means drop-in integration for existing apps.
  • •File-based source and sink with JSON Lines support covers common ETL patterns.
Weaknesses
  • •Pre-release with no Maven publication yet — requires local build and publish.
  • •Missing windowing, groupBy, and event-time semantics limits real streaming use cases.
Target Audience

Post Description

hello! felt inspired by reading about duckdb, how its embedded, and merging that with my interest in data engineering, pipelines and such.

just a little you project i thought i would share. no bigger aspirations than "this could be cool" and thought i would share with the community.

feedback welcomed
