Question

A data engineer is using Snowflake Notebooks to perform a series of transformations on a large dataset. After executing a cell containing a complex SQL query that includes user-defined functions (UDFs), the cell's execution status remains 'Running' for an unexpectedly long time. What are the MOST likely reasons for this prolonged execution time?

Options

  • AThe UDFs within the query are inefficient and causing performance bottlenecks.
  • BThe Snowflake warehouse is under-provisioned for the size and complexity of the query.
  • CThe data being processed is heavily skewed, leading to uneven workload distribution across
  • DThe Snowflake Notebook session has timed out due to inactivity.
  • EThe cell is waiting for a lock on a table or object that is currently being modified by another
