This video tutorial introduces cluster sharding, explaining its purpose and how it functions within a distributed system. It covers the concept of shard regions and the role of a sharding coordinator, using scenarios to illustrate the mechanism. The tutorial then guides viewers through implementing cluster sharding, including persistence configuration and message handling. By the end, viewers will understand how to distribute actors across nodes and manage stateful actors efficiently.
