NEW QUESTION # 566
What Snowflake objects or services can be used to automatically load data from files as soon as. They are available in an external staged (Select TWO).
Answer: B,E
Explanation:
* Snowflake provides mechanisms to automatically load data from files in external stages (like Amazon S3 or Azure Blob Storage).
* The correct methods include:
* Snowpipe (B):
* Snowpipe is Snowflake's continuous data ingestion service, which automatically detects and loads new files from external stages into Snowflake tables.
* It provides near real-time data loading with low-latency ingestion.
Example:
CREATE PIPE my_pipe
AUTO_INGEST = TRUE
AS COPY INTO my_table FROM @my_stage FILE_FORMAT = (TYPE = 'CSV');
* Task (C):
* Tasks can be scheduled to run at specific intervals or triggered in response to events.
* You can create a task to call a stored procedure, which, in turn, uses Snowpipe or COPY INTO to load data.
Example:
CREATE TASK my_task
SCHEDULE = '5 MINUTE'
AS
CALL load_data_procedure();
Why Other Options Are Incorrect:
* A. Stream: Streams track changes in a table for change data capture (CDC) but do not directly load data from files.
* D. Directory table: Snowflake does not have a "directory table" object for managing external file ingestion.
* E. User-Defined Function (UDF): UDFs are used for custom logic within SQL queries, not for data loading.
