Changes:
- Added JaCoCo to pom.xml with a 100% instruction, line, and branch coverage rule scoped to org.example.videoclips.folder.
- Added src/test/java/org/example/videoclips/folder/FolderSchedulerDirectoryInitializerTest.java.
- Added src/test/java/org/example/videoclips/folder/FolderVideoScanSchedulerTest.java.
- Adjusted the scanner comparator in src/main/java/org/example/videoclips/folder/FolderVideoScanScheduler.java to keep deterministic ordering without an uncovered comparator branch.
Verification: mvn -q verify passed. The generated JaCoCo report shows org.example.videoclips.folder at 100% instruction, line, and branch coverage.
Scope note: this enforces 100% coverage for the new scheduler package, not the whole existing service. Project-wide 100% would be a much larger pass across pre-existing classes. The next
scheduler milestone is repeat-prevention by moving selected inputs to the working folder before processing.
I added autoscaling-ready queue metrics in src/main/java/org/example/videoclips/observability/DatabaseQueueMetricsBinder.java:13, backed by new queue repository counters, and enabled Prometheus scraping via src/main/
resources/application.properties:3 plus the Prometheus registry dependency in pom.xml:43. The policy itself is documented in docs/autoscaling-policies.md:1, including worker/API scaling rules and a sample KEDA ScaledObject.
Coverage for the new gauges is in src/test/java/org/example/videoclips/observability/DatabaseQueueMetricsBinderTest.java:14.
upload part URLs and signed clip download URLs when video-clipping.storage=s3. The current in-memory adapter remains the default. I also added the supporting configuration fields in src/main/
java/org/example/videoclips/config/VideoClippingProperties.java and default values in src/main/resources/application.properties.
The queue port now has a durable database-backed implementation in src/main/java/org/example/videoclips/queue/DatabaseBackedClipJobQueueAdapter.java. It persists queue messages in a new
queue_messages table from src/main/resources/db/migration/V2__queue_messages.sql, polls them on a schedule, and dispatches them through the existing processor. I updated src/main/java/org/
example/videoclips/processing/ClipProcessor.java so processing failures propagate back to the queue adapter instead of being swallowed.
I also enabled scheduling in src/main/java/org/example/videoclips/VideoClippingApplication.java, added the AWS SDK dependency in pom.xml, and updated src/main/resources/application-jpa.properties
so the JPA profile uses the database queue by default.
main/java/org/example/videoclips/infrastructure/InMemoryVideoAssetRepository.java and the new src/main/java/org/example/videoclips/persistence/JpaVideoClippingRepository.java behind it. The JPA
path includes entity models, Spring Data repositories, a mapper, and a Flyway baseline migration at src/main/resources/db/migration/V1__init_video_clipping.sql. I also added the required
dependencies in pom.xml.
The default runtime still uses the in-memory repository via video-clipping.repository=memory, so existing behavior stays intact. There’s now a ready-to-use JPA profile in src/main/resources/
application-jpa.properties that uses H2 in PostgreSQL mode for local bring-up. That gives the codebase a real persistence lane without forcing the switch yet.
