About this course and the Instructor1:47

Do you use transformation when loading data using the COPY command?0:52
What is needed to establish connectivity between snowflake and cloud storage ?1:53
How can we ingest data without using snowpipe, COPY or 3rd party ETL like DBT ?0:51
Explore ingesting data into Snowflake using external tables from cloud storage, inserting into a target table, and streaming via streams for near real-time loads, without snowpipe, copy, or DBT.
You received files from your new vendor, you are aware of the layout of ..?1:07
How will you setup a process of automatic validation and quality control of ..?0:59
Once a file is loaded with the COPY command can you reload the file again ?1:08
What is the data loading strategy in your project ?2:33
When ingesting data from data lake, are most of your files in parquet format ..?2:45

You want to truncate a table in snowflake, can you use a UDF to do so ?0:48
What are the benefit of using stored procedure and UDF ?2:45
Have you created stored procedures in your project, what dd you use them for ?0:35
What language does snowflake UDF support ?0:36
Snowflake UDFs support SQL, Python, JavaScript, and Java. In practice, answer with SQL for UDFs and stored procedures unless you are confident in JavaScript or Java.

In which scenario is using snowpipe not recommended in snowflake ?1:34
Why would you use snowpipe instead of batch job in your project data load?0:56
There are several files in cloud storage that was received 11 days ago, you ..?1:32
Rely on cloud storage notifications; Snowpipe ingests new files and ignores files created before it. Load older files with a copy command, or alter pipe refresh covers only seven days.
What is snowpipe.What are its advantages ?2:05
How do we pause execution of a pipe which is skipping files due to data issues ?1:36
What are the steps for setting up Snowpipe ?1:28
Provide me a scenario in your project where you used snowpipe?0:57
How can you monitor and troubleshoot snowpipe errors?8:32
Learn to monitor and troubleshoot snowpipe by checking pipe status, reviewing copy history, validating loads, fixing data issues, and restarting to process new files.
Due to a few bad rows in the file your snowpipe load is skipping files. How ..?0:40

What is a task , What are its advantages ?2:52
How can you monitor tasks in snowflake ?9:02
When a task is created is it Active or inactive by Default ?3:04
What would happen if we created a task without a warehouse ?4:57
What is the maximum Number of tasks that a DAG can have +1 ?1:39
You changed a table column causing a task to fail, how will you handle it ?1:16
Suspend the failing task to prevent repeats, remove it from the task tree, perform table maintenance, fix and test changes, then resume the task with alter task remove after clause.
Explain a scenario in your project where you have used tasks ? 3 Use Cases4:22
Demonstrate three use cases of tasks in a Snowflake project: daily storage metrics with a stored procedure, task-driven streams for CDC, and 60-minute refreshed reporting tables.
How will you find dependency information between tasks on a tree of tasks?11:14

What is a resource monitor? How would you ensure that a badly written query ..?1:26
Learn how Snowflake's resource monitors manage credits in a metered service by setting limits, triggering alerts, and suspending warehouses to prevent excessive credit consumption from poorly written queries.
How many Resource monitors can you have in your account ?4:05
Snowflake allows one account-level resource monitor; warehouse-level monitors are possible, but a warehouse cannot belong to multiple account-level monitors, and thresholds trigger suspends and notifications as credit quotas are reached.
What actions can be taken inside a resource monitor ?1:46

What is a stage in snowflake ?0:58
In what scenario do you see the need for project to use internal stage ?0:33
How can you determine how many files are there in a stage ?0:32
What are the different type of internal stages in snowflake ?1:18
Explore the three internal Snowflake stages: user stage, table stage, and named internal stage, and learn how privileges, automatic creation, and loading data across stages work, including listing files.
How can you add, download and remove files from an Internal Stage ?0:43
You have 100 files on a server which is on premises that you want to upload to ?0:57

How does a stream become empty ? How can you purge a stream ?0:55
Can you join a stream and table ?0:43
Learn how to join a stream and a table in Snowflake using the join keyword for an append-only stream, and the merge command to consume updates, deletes, and inserts.
In what scenario did you use streams in your project ? Use Case 11:22
In what scenario did you use streams in your project ? Use Case 21:45
A 1 GB file arrives and must be ingested near real time. Snowpipe is unsuitable; create an external table, define a stream, and poll data into Snowflake.
What is change tracking on a table ? Why is it used instead of streams ?1:23
What is a stream ?1:18
Explore Snowflake streams as near real time change data capture to propagate inserts, updates, and deletes to a target table, and learn how to create streams with create stream command.
What are the different type of streams ?2:32
