Something I didn't get :
SQL server won't callback clients [or application-server] informing that new data is available. So how do you poll it? A query in periodic loop? Some other way? How much that scales, or how much load does that create on the server?
- lukaszkorecki 4y agoPostgres has a NOTIFY feature: https://www.postgresql.org/docs/current/sql-notify.html https://www.postgresql.org/docs/current/sql-notify.html that can be used for this if you don't want to poll.
