commit a6a13fe Author: Neil Best <neil.best@databricks.com> Date: Thu May 23 16:39:58 2024 -0500 improve TransformationDescriberTest commit 1f145aa Author: Neil Best <neil.best@databricks.com> Date: Thu May 23 15:25:29 2024 -0500 Add descriptive job group IDs and named transformations This makes the Spark UI more developer-friendly when analyzing Overwatch runs. Job group IDs have the form <workspace name>:<OW module name> Any use of `.transform( df => df)` may be replaced with `.transformWithDescription( nt)` after instantiating a `val nt = NamedTransformation( df => df)` as its argument. This commit contains one such application of the new extension method. (See `val jobRunsAppendClusterName` in `WorkflowsTransforms.scala`.) Some logic in `GoldTransforms` falls through to elements of the special job-run-action form of Job Group IDs emitted by the platform but the impact is minimal relative to the benefit to Overwatch development and troubleshooting. Even so this form of Job Group ID is still present in initial Spark events before OW ETL modules begin to execute.

Removed a level of indirection and unnecessary conditional branching in definition of chained `lookupWhen` transformations. Moved defintions to have references to `PipelineTable` objects in scope rather than passing them by argument.
