Is it true or false that a query plan can only be used for completed queries?

  1. True

  2. False

  3. Only for queries over a certain duration

  4. Depends on user permissions

The correct answer is: False

The statement is false because query plans in Snowflake can be generated and examined for queries that are currently in progress, as well as those that have been completed. Query plans provide insights into how the Snowflake engine processes queries, including the various stages involved in executing a query. This can be incredibly useful for troubleshooting or optimizing ongoing queries, not just those that have already finished. The capability to analyze both ongoing and completed queries allows users to optimize performance and make informed decisions about how to alter their queries for better efficiency. Consequently, the assertion that a query plan is only applicable to completed queries does not hold true, as it applies to any query being processed within Snowflake’s architecture.
