mattcasters opened a new pull request, #8178: URL: https://github.com/apache/hop/pull/8178
Port Kettle **Output steps metrics** as a Hop-native **Output transform metrics** transform. Fixes #3003 ## What A local-engine generator that waits for listed sibling transform copies to finish, then emits one metrics row per copy (name, plugin id, line counters, rejected rows, duration). Incoming hops are not consumed and are treated as an error because they can deadlock the pipeline. ## Why Pipeline Logging / Execution Information cover project-wide monitoring, but they do not replace this in-pipeline transform for Kettle/PDI migrations. ## How - New plugin `plugins/transforms/transformsmetrics`, plugin id `TransformsMetrics` (deprecated extra id `StepsMetrics`). - Metadata is `@HopMetadataProperty` with Hop `transform*` XML keys. The dialog uses grouped `GuiCompositeWidgets` tabs plus a `TableView` extra group. - Runtime follows `BlockUntilTransformsFinish` wait semantics, then emits metrics instead of passing rows through. - Kettle import maps `StepsMetrics` → `TransformsMetrics` and `step*` tags → `transform*` (including the Kettle `steplineswrittentfield` typo). Stored output field *values* are left unchanged. ## Tests - Unit: XML round-trip, `getFields`, `check()` (`TransformsMetricsMetaTest`) - Import: Kettle snippet rewrite (`KettleImportTransformsMetricsTest`) - Integration: `0110-output-transform-metrics` with a golden dataset ## Docs User-manual page, sample pipeline, Transforms and Fields tab screenshots. ------------------------ Thank you for your contribution!
