Databricks DE-PRO Data Ingestion Guide

Study Databricks DE-PRO Data Ingestion: key concepts, common traps, and exam decision cues.

This domain is smaller by weight, but it creates a lot of later failures. Weak ingestion design produces bad downstream quality, poor recoverability, and expensive replay behavior.

Work this chapter in order

Lesson	Focus
2.1 Auto Loader & Sources	Learn how DE-PRO frames source-type and ingestion-pattern choices.
2.2 Append-Only & Streaming	Learn how the exam separates append-only Delta design from streaming semantics.

Fast routing inside this chapter

If the question is really about…	Go first to…
source formats, file discovery, message buses, or Auto Loader	2.1 Auto Loader & Sources
append-only Delta, batch-plus-streaming ingest, or stateful streaming behavior	2.2 Append-Only & Streaming

What strong answers usually do

pick the ingestion pattern that matches the source-arrival behavior
keep append-only and stateful streaming concerns conceptually separate
protect replay safety at the ingestion boundary
