Snowflake - Build and Architect Data Pipelines Using AWS - Lab - Implement Append-Only Streams

The video tutorial explains the concept of append only streams, detailing their creation, execution, and limitations. It demonstrates how to create a stream, insert data, and consume it, while highlighting that append only streams do not capture updates or deletes. The tutorial concludes with a preview of future topics, including streams in transactions and a mini project using streams and Snowpipe.

What is the primary difference between append-only streams and other types of streams?

• Append-only streams can capture updates and deletes.

• Append-only streams only capture newly inserted rows.

• Append-only streams require complex syntax.

• Append-only streams are slower than other streams.

What is the purpose of the 'append only' clause in the stream creation syntax?

• To allow updates and deletes.

• To increase the speed of data capture.

• To ensure only new rows are captured.

• To enable complex data transformations.

How does the append-only stream behave after consuming data into the production table?

• It resets and becomes empty.

• It retains all captured data.

• It duplicates the data.

• It captures updates and deletes.

What happens when an update is made to the raw table in an append-only stream?

• The stream throws an error.

• The update is captured by the stream.

• The stream captures both the old and new values.

• The update is ignored by the stream.

Which of the following operations is NOT captured by an append-only stream?

• Inserting new rows

• Updating existing rows

• Deleting rows

• Both updating and deleting rows
