Hi,
suppose a lot of clients are using the database server with different
complex queries simultaneously. I understand that all clients are
equal so clients with large tasks would hamper clients with small
tasks.
It would be nice if a client could say: hey I know I have a large task
/ query please set me to a low priority. So the server would withdraw some
cpu and io cycles from this task.
On a per process basis one would do this with 'nice' but how could
that be applied to the postmaster/postgres mechanism?
Or in a more complex mod_perl scenario where httpd processes don't
open/close connections for new requests (by Apache::DBI).
Something like SET PRIORITY...
Any comments?
Dirk
