What aspect of an executed query is represented by the remote disk I/O statistic of the Query Profile in Snowflake?
What aspect of an executed query is represented by the remote disk I/O statistic of the Query Profile in Snowflake?
The remote disk I/O statistic of the Query Profile in Snowflake represents the time spent reading and writing data from and to remote storage when the data being accessed does not fit into either the virtual warehouse memory or the local disk. This indicates that operations are occurring beyond just the memory and local disk, involving interaction with remote storage resources.
I think it's D C would assume writing to local disk is also "remote disk IO" which doesn't seem to be the case
I agree its D
C would assume writing to local disk is also "remote disk IO" which doesn't seem to be the case
"local disk" is remote storage, with respect to warehouse memory. So, I feel C is correct.
I think the correct answer is A B - not correct C - the correct metric for that would be Bytes spilled to local storage D - the correct metric for that would be Bytes spilled to remote storage A - correct, we're accessing the remote disk (the Storage Layer) to retrieve the data for the query. https://community.snowflake.com/s/article/Performance-impact-from-local-and-remote-disk-spilling https://community.snowflake.com/s/article/Performance-impact-from-local-and-remote-disk-spilling https://community.snowflake.com/s/article/Performance-impact-from-local-and-remote-disk-spilling
Correction: C wouldn't happen the way it's described in the question. In case with C, data will be written to local storage (of the warehouse)
Changing my mind to B. We can cross-reference the options against this doc: https://docs.snowflake.com/en/user-guide/ui-query-profile#statistics A - Pruning B - IO C - Spilling D- Spilling
I just ran a couple of sample queries and I change my mind back to option A. Remote disk I/O means we're accessing the data from the storage layer.
If you run a query, look for it in the Activity History, click on TableScan, you will see that most of that may be Remote Disk I/O (option A)

Changing to D based on points by Ukpino
