Event-driven OneLake pipeline desktop tool with auto-merge Upsert, Python reporting, and Teams alert

• Event-driven trigger: A OneLake FileCreated event on the Files/inbox folder launches the pipeline automatically as soon as a .csv file lands, with a filter matching files whose subject ends in .csv. No schedule, no manual invocation.
• Filename resolution from the event: A Set variable activity extracts the file name from the trigger event payload, falling back to a pipeline parameter when the run is started manually. The resolved value is reused by every downstream activity.

An observability database aims to ingest, analyze and store Metrics, Tracing and Logging data.

Event-driven OneLake pipeline with automated Upsert merge and Python reporting

• Event-driven orchestration: A trigger bound to OneLake file-created events watches the designated inbox folder and launches the pipeline automatically the moment a matching file lands. No scheduler, no manual run, no polling loop; the arrival of data is itself the execution signal.
• Parameterless-by-design entry point: The trigger event carries the file name through to the pipeline, where a variable resolution step coalesces the event payload with an optional manual parameter. The same pipeline supports both automatic and on-demand invocation without code changes or duplicated definitions.
