I want to raise the priority for this ticket. Ultimately, we want to have read replicas in different regions. In order to reduce the latency, we want to have “Standy” pageserver nearby

shanyp commented 1 year ago

Don't we want the replica to be of a specific tenant?

vadim2404 commented 1 year ago

yes, we need to replicate data per tenant

@LizardWizzard @hlinnaka before starting the deep dive discussion here, do we have this already partially covered for the read-only state for tenant relocation?

LizardWizzard commented 1 year ago

It depends on what is meant by HA. What are the requirements?
