In this lesson
Prepare for the Databricks Certified Data Engineer Associate exam. In this lesson: serverless compute and its limitations, classic compute (all-purpose and job compute, access modes, instance pools), SQL warehouses, and how to follow costs with DBUs and the billing system table. Includes three original practice questions.
Preview the topics
- A data scientist has an old notebook that uses the RDD API and some R code, and it must now run as a scheduled job. Which compute fits this job?
- A nightly notebook builds the silver tables on an all-purpose cluster that engineers share during the day, and it often stays on all night. The team wants the nightly run to cost less, with no idle time. What should they change?
- Twenty analysts refresh their sales dashboards every morning: the queries pile up at 9 a.m., and nothing runs after noon. Which compute fits best?
