.net - Is there a scalable alternative to SQL Server Query Notifications for raising events in an application from SQL Server? -

-

sql server query notifications great tool, doesn't seem built scale well. every application wants/needs notifications has keep open connection database duration of time wants notifications (typically entire time application running).

i open creative solutions. off top of head thought of putting service on server subscribe sql server query notifications notify client applications. in case have 1 database connection open (and why not leave open time), , client applications subscribe service notification.

ideas??

you may want building own solution using sql server service broker , db_mail or external activators.
