NEW QUESTION # 332
Snowflake computes and adds partitions based on the defined partition column expressions when an external table metadata is refreshed.
What are the Correct Statements to configure Partition metadata refresh in case of External Tables?
Answer: C,D
Explanation:
Explanation
Snowflake strongly recommend partitioning your external tables, which requires that your underly-ing data is organized using logical paths that include date, time, country, or similar dimensions in the path.
Partitioning divides your external table data into multiple parts using partition columns.
An external table definition can include multiple partition columns, which impose a multi-dimensional structure on the external data.
Partitions are stored in the external table metadata.
Benefits of partitioning include improved query performance.
Because the external data is partitioned into separate slices/parts, query response time is faster when processing a small part of the data instead of scanning the entire data set.
Based on your individual use cases, you can either:
Add new partitions automatically by refreshing an external table that defines an expression for each partition column.
Add new partitions manually.
Partition columns are defined when an external table is created, using the CREATE EXTERNAL TABLE ...
PARTITION BY syntax.
After an external table is created, the method by which partitions are added cannot be changed.
Partitions Added Automatically
An external table creator defines partition columns in a new external table as expressions that parse the path and/or filename information stored in the METADATA$FILENAME pseudocolumn.
A partition consists of all data files that match the path and/or filename in the expression for the partition column.
The CREATE EXTERNAL TABLE syntax for adding partitions automatically based on expres-sions is as follows:
CREATE EXTERNAL TABLE
<table_name>
( <part_col_name> <col_type> AS <part_expr> )
[ , ... ]
[ PARTITION BY ( <part_col_name> [, <part_col_name> ... ] ) ]
Snowflake computes and adds partitions based on the defined partition column expressions when an external table metadata is refreshed.
By default, the metadata is refreshed automatically when the object is created.
In addition, the object owner can configure the metadata to refresh automatically when new or up-dated data files are available in the external stage.
The owner can alternatively refresh the metadata manually by executing the ALTER EXTERNAL TABLE ...
REFRESH command.
The metadata for an external table can be refreshed automatically using the event notification ser-vice for your cloud storage service.

@% character combination identifies a table stage.
NEW QUESTION # 334
A Data Engineer is building a pipeline to transform a 1 TD tab e by joining it with supplemental tables The Engineer is applying filters and several aggregations leveraging Common TableExpressions (CTEs) using a size Medium virtual warehouse in a single query in Snowflake.
After checking the Query Profile, what is the recommended approach to MAXIMIZE performance of this query if the Profile shows data spillage?
Answer: A
Explanation:
Explanation
The recommended approach to maximize performance of this query if the Profile shows data spillage is to increase the warehouse size. Data spillage occurs when the query requires more memory than the warehouse can provide and has to spill some intermediate results to disk. This can degrade the query performance by increasing the disk IO time. Increasing the warehouse size can increase the amount of memory available for the query and reduce or eliminate data spillage.
NEW QUESTION # 335
A company is using Amazon S3 to build a data lake. The company needs to replicate records from multiple source databases into Apache Parquet format.
Most of the source databases are hosted on Amazon RDS. However, one source database is an on-premises Microsoft SQL Server Enterprise instance. The company needs to implement a solution to replicate existing data from all source databases and all future changes to the target S3 data lake.
Which solution will meet these requirements MOST cost-effectively?
Answer: C
Explanation:
Amazon DMS can perform a one-time full load of each source (including the on-prem SQL Server) and then capture ongoing changes (CDC), delivering them directly to S3 in Apache Parquet format. Using a single DMS replication task per source minimizes infrastructure, operational overhead, and cost.
NEW QUESTION # 336
The company stores a large volume of customer records in Amazon S3. To comply with regulations, the company must be able to access new customer records immediately for the first
30 days after the records are created. The company accesses records that are older than 30 days infrequently.
The company needs to cost-optimize its Amazon S3 storage.
Which solution will meet these requirements MOST cost-effectively?
Answer: A
Explanation:
S3 Standard-IA (Infrequent Access) is ideal for data that is accessed less frequently but requires immediate access when needed. Since the company needs immediate access to customer records for the first 30 days and infrequent access afterward, applying an S3 lifecycle policy to automatically transition the data to S3 Standard-IA after 30 days provides a cost-effective solution. This way, records remain easily accessible during the initial 30 days and are moved to a cheaper storage tier when they are accessed less often.
S3 Intelligent-Tiering automatically moves data between frequent and infrequent access tiers based on access patterns, but it incurs additional monitoring and automation charges. This option is typically more expensive compared to S3 Standard-IA if the access pattern is well understood (like in this case, where data is accessed frequently for the first 30 days and infrequently thereafter).
S3 Glacier Deep Archive is a low-cost storage option for archival data that is rarely accessed and requires hours for retrieval. It does not meet the requirement for immediate access to records after 30 days.
Storing all data in S3 Standard-IA is more expensive during the first 30 days when the data is accessed frequently. S3 Standard is more cost-effective for frequently accessed data during that period.
