BDR AutoScale
Since we used BDR rather extensively in Chapter 13, High Availability with Multi-Master Replication, we figured we'd share this here as well. The BDR development roadmap currently includes a feature named AutoScale. The idea, in this case, is to leverage the multinode nature of a BDR cluster and also integrate sharding concepts, as we discussed in this chapter.
Early planning suggests that AutoScale will leverage the automated management of PostgreSQL 10-style declarative partitions by including multinode node affinity. This means that writing data to one multi-master node can distribute that information among a subset of the existing cluster within partition tables for better scaling and maintenance purposes.
