Can same topic be configured to multiple s3 buckets? - amazon-web-services

Question

I am trying to refresh external table using SNS in snowflake.
I have followed this tutorial to refresh.
https://www.youtube.com/watch?v=PCNa3d6rMO0
it is working as expected.but when I use same topic to trigger another table in another S3 bucket. Can't I use the same topic and create event notifications in Bucket2?
Here is my Access Policy :

I'm not a Snowflake person, but it appears that the linked demonstration is Configuring Amazon SNS to Automate Snowpipe Using SQS Notifications
.
According to that documentation, the following code is used to create the pipe:
create pipe snowpipe_db.public.mypipe
auto_ingest=true
aws_sns_topic='<sns_topic_arn>'
as
copy into snowpipe_db.public.mytable
from #snowpipe_db.public.mystage
file_format = (type = 'JSON');
The copy into snowpipe_db.public.mytable seems to be hard-coded for a destination table. It seems that each Snowpipe can only be used to load data into a single table.
Therefore, you would likely need to use a different Snowpipe, and therefore a different SNS Topic and SQS queue, if you wish to load data into a different table.
