Which of the following statements are true regarding the use of user-defined functions (UDFs) in Snowflake to optimize query performance, especially when compared to equivalent SQL expressions? (Select all that apply)

• A.UDFs can sometimes improve code readability by encapsulating complex logic, but this rarely translates into significant performance gains.
• B.Snowflake UDFs, especially those written in Java or Python, can introduce performance overhead due to the cost of invoking the external runtime environment.
• C.SQL UDFs generally perform better than Java or Python UDFs because they are executed natively within the Snowflake engine.
• D.UDFs can be useful when the same complex calculation needs to be performed multiple times within a single query, potentially reducing code duplication and improving maintainability, thereby indirectly improving performance by simplification.
• E.External functions and UDFs are the same, both reside outside snowflake.

You are tasked with building a data ingestion pipeline to retrieve data from a transactional database using Change Data Capture (CDC).The source database is a MySQL instance. Which of the following approaches is MOST suitable for efficiently retrieving and loading the changed data into Snowflake while minimizing latency?

• A.Use a scheduled task to periodically query the MySQL database for records modified within a specific time window and load them into Snowflake using COPY INTO. Implement a timestamp-based or version-based change tracking mechanism in the query.
• B.Configure MySQL binary log replication to a cloud storage location (e.g., AWS S3, Azure Blob Storage, Google Cloud Storage) and use Snowpipe to continuously ingest the binary log files into Snowflake.
• C.Use a third-party CDC tool that supports MySQL as a source and Snowflake as a target. Configure the tool to capture changes from the MySQL binary logs and stream them directly into Snowflake tables.
• D.Create a Snowpark Python UDF that connects to the MySQL database, reads the binary logs, and applies the changes directly to Snowflake tables.
• E.Create a Snowflake external table pointing to the MySQL database. Use the external table to read data directly from the MySQL database into Snowflake tables.
