Hi All,
I have a very basic question about streaming replication feature of Postgres.
Let’s assume I have servers A, B, C, D, & E with postgres installed with streaming replication as follow:
A à B ( sync replication )
A à C ( async replication )
A à D ( async replication )
A à E ( async replication )
A is master & rest are slaves.
Now my question is:
Assume replication link between A & B may/may not stable. If A goes down, how will I choose my new master from slaves? What are criteria to choose new master?
Thanks,
Sacheen Birhade
