[All Databricks Certified Data Engineer Associate Questions]

A data engineer has developed a data pipeline to ingest data from a JSON source using Auto Loader, but the engineer has not provided any type inference or schema hints in their pipeline. Upon reviewing the data, the data engineer has noticed that all of the columns in the target table are of the string type despite some of the fields only including float or boolean values.

Which of the following describes why Auto Loader inferred all of the columns to be of the string type?

Show Suggested Answer Hide Answer
Suggested Answer: A

To grant full privileges on a table such as 'sales' to a group like 'team', the correct SQL command in Databricks is:

GRANT ALL PRIVILEGES ON TABLE sales TO team;

This command assigns all available privileges, including SELECT, INSERT, UPDATE, DELETE, and any other data manipulation or definition actions, to the specified team. This is typically necessary when a team needs full control over a table to manage and manipulate it as part of a project or ongoing maintenance.

Option B is the answer, obviously. Unless the data engineer is a secret string enthusiast, in which case, kudos to them.

Makes sense, since JSON data is text-based.

That's a good point, Dannette. It could be a combination of both factors affecting the schema inference.

But isn't it also because JSON data is a text-based format, which might have influenced the inference?

I think the reason Auto Loader inferred all columns as string is because it cannot infer the schema of ingested data.
