Score: 69/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 82, release rhythm 35, longevity 100
- inputs: {"age_days": 2326, "days_push": 110, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
A collection of hands-on lab exercises and solutions accompanying the official Apache Flink training documentation. It provides a Gradle-based Java project with taxi ride data streams, exercises, tests, and reference solutions for learning stream processing with Flink.

## Use cases
- learn apache flink stream processing
- practice writing flink datastream jobs
- hands-on exercises for stateful stream processing
- prepare for building flink etl pipelines
- run and debug flink programs in an ide
- learn event-time processing and windowing in flink

## When to choose
- you are new to Apache Flink and want guided, hands-on exercises
- you want runnable examples with tests and solutions to compare against
- you prefer learning by building Java projects in an IDE

## When to avoid
- you need production-ready Flink application scaffolding rather than tutorials
- you want training for other stream processors like Spark or Kafka Streams
- you need Scala or Python (PyFlink) exercises

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools, etl, streaming, data-science
- domain: big-data, tutorials, developer-tools
- platform: jvm, cross-platform, cli
- tags: apache-flink, stream-processing, training-exercises, java, gradle, taxi-data-generator, data-engineering
