A Snowflake user would decide to use a materialized view instead of a regular view primarily when the base tables do not change frequently. Materialized views store the result of the view query and update it as the underlying data changes, making them ideal for situations where the data is relatively static and query performance is critical. By precomputing and storing the query results, materialized views can significantly reduce query execution times for complex aggregations, joins, and calculations.

The user property 'MINS TO BYPASS MFA' in Snowflake allows temporary bypass of MFA for a user, which can be set by an account administrator without contacting Snowflake Support2.

The query acceleration service in Snowflake is beneficial for workloads that include on-demand data analyses. This service optimizes query performance by dynamically allocating additional resources to execute queries faster, particularly useful for ad-hoc analysis where data volume and complexity can vary.

With reader accounts, the provider pays for:
* Storage of shared data
* Compute used by the reader account
The consumer does not pay, as the infrastructure is provisioned and managed by the provider.
