Behind the scenes of Aerospike’s Cross Datacenter Replication (XDR)
Aerospike’s Cross data center replication (XDR) is the module responsible for shipping data across multiple datacenters, typically across geographical locations. Distributed systems come with many unique challenges and XDR is equipped to handle them.
In this talk we will take a look at the internals of XDR. We will get into some details of how we achieve high performance by exploiting cache friendliness and core affinity. We will also cover challenges we face to keep data consistent. Many things can fail in a distributed system. In this talk we will discuss some of the common failures like source node failure, destination node failure and network issues.
