Actions Reference

Actions are the building block of Lakehouse Plumber flowgroups.

Actions Overview

Actions come in four top-level types:

Type	Purpose
Load	Bring data into a temporary view (e.g. CloudFiles, Delta, JDBC, SQL, Python).
Transform	Manipulate data in one or more steps (SQL, Python, schema adjustments, data-quality checks, temp tables…).
Write	Persist the final dataset to a streaming_table or materialized_view.
Test	Validate data quality using DLT expectations in temporary tables (uniqueness, referential integrity…).
