Automatic Clustering is the Snowflake service that seamlessly and continually manages all reclustering, as needed, of clustered tables. Automatic clustering consumes credits, so if automatic clustering is enabled or resumed on a table and it has been a while since the table was clustered, the reclustering activity will start and corresponding credits will be consumed. Similarly, defining a clustering key on existing table or changing the clustering key on clustered table will trigger reclustering and credit charges.

Since the credit charges are consumed automatically, it is important for users and administrators to track the reclustering activity, prevent any unexpected charges and ensure that only intended actions are resulting in credit consumption.

This test monitors the Snowflake cloud and collects the credit usage-related metrics for the Automatic Clustering service in real time, using which administrators can make informed decisions on planning the reclustering activity and avoid any unintended actions leading to credit consumption.

Outputs of the test: One set of results for each Snowflake service account being monitored.
