Read-write and read-only compute instances read data from a single source, ensuring a high degree of data consistency
I found this, but it says that Neon read replicas are asynchronous, so I wanna know if it’s strong consistency.
It seems there are two ways to make reading strong consistent,
- When read from read-only replica, read WAL(small than the start point of the read transaction) + page-server
- When RW commits a transaction, make sure that the WAL of that transaction is “propagated” to read-replicas
but I can’t find things in Neon document.
pls correct me if I misunderstood anything, thank you.
