Topic #: 5

[All Databricks Certified Data Engineer Associate Questions]

A data engineer needs to create a table in Databricks using data from their organization's existing SQLite database.

They run the following command:

Which of the following lines of code fills in the above blank to successfully complete the task?

Aorg.apache.spark.sql.jdbc

Bautoloader

CDELTA

Dsqlite

Eorg.apache.spark.sql.sqlite

Show Suggested Answer

Suggested Answer: A

Auto Loader in Databricks utilizes Spark Structured Streaming for processing data incrementally. This allows Auto Loader to efficiently ingest streaming or batch data at scale and to recognize new data as it arrives in cloud storage. Spark Structured Streaming provides the underlying engine that supports various incremental data loading capabilities like schema inference and file notification mode, which are crucial for the dynamic nature of data lakes.

Wait, is it really A? I thought SQLite had its own connector.

I feel like sqlite could be relevant since we're dealing with an SQLite database, but I'm not confident if that's the correct syntax for Databricks.

I practiced a similar question where we had to specify the right package for a database connection, and I think it was related to org.apache.spark.sql.jdbc.

I'm not entirely sure, but I think autoloader is more for streaming data, so that might not fit here.

I remember something about using JDBC for connecting to databases, so maybe option A is the right choice?

Alright, I've got a strategy. I'll start by considering which option best matches the context of the question and the Databricks command provided. That should help me narrow it down.

I'm a bit confused here. The question mentions a SQLite database, but none of the options seem to directly reference that. I'll need to think this through more carefully.

Okay, I think I've got this. The blank needs to be filled with the appropriate Spark SQL package to connect to a SQLite database. Let me double-check the options.

I'm feeling pretty confident about this one. The key is recognizing that we need to use the appropriate Spark SQL package to connect to the SQLite database. I think I know the right answer.

Ah, this is right in my wheelhouse! I've studied MIL-STD-499B extensively, so I'm confident I can identify the correct benefits listed in the question. Time to put that knowledge to use.

But the question is asking about creating a table in Databricks using data from a SQLite database, so I think A) org.apache.spark.sql.jdbc makes more sense.
