Getting Started With Active-Active Geo-Distribution for Redis Apps With CRDTs

Today, Redis applications can take advantage of a few types of replication:

LAN-based replication: Tuned for LAN characteristics; low latency and high bandwidth networks with only a few retransmissions. WAN-based replication: Tuned for WAN characteristics; high latency and low bandwidth networks with high network "noise" ratio.

In the upcoming version of Redis Enterprise 5.0, we are delivering a new flexible, multi master replication technology built for WAN. The new capability allows active-active geo-distributed Redis deployments using the magic of CRDTs (conflict-free replicated data types). CRDTs simplify development of active-active systems and automatically resolve conflicting writes. Combined with Redis datatypes, CRDTs provide a mechanism that can easily help you develop active-active geo-distributed systems that can intelligently handle conflicting writes.
