What is a characteristic of event notifications in Snowpipe?

Event notifications in Snowpipe are messages sent by cloud storage providers to notify Snowflake of

new or modified files in a stage. Snowpipe uses these notifications to trigger data loading from the

stage to the target table. When a pipe is paused, event messages received for the pipe enter a

limited retention period, which varies depending on the cloud storage provider. If the pipe is not

resumed within the retention period, the event messages will be discarded and the data will not be

loaded automatically. To load the data, the pipe must be resumed and the COPY command must be

executed manually. This is a characteristic of event notifications in Snowpipe that distinguishes them

from other options. Reference: Snowflake Documentation: Using Snowpipe, Snowflake
