How should I understand "backend_weight" config variable?
For example, I have two postgres servers: "local" and "remote".
I would like to execute all SELECT operations on the "local" server only
/ mostly.
What backend_weight should I use?
backend_hostname0 = 'local'
backend_weight0 = 1
backend_hostname1 = 'remote'
backend_weight1 = 0
This one.
Thanks.
Out of curiosity, how would be such values handled?
backend_hostname0 = 'postgres1'
backend_weight0 = 0
backend_hostname1 = 'postgres2'
backend_weight1 = 1
backend_hostname1 = 'postgres3'
backend_weight1 = 2
postgres1 should not get any reads.
postgres2 should get 33,3(3)% reads.
postgres2 should get 66,6(6)% reads.
Is my reasoning correct?
