Tie Breaker Functionality for Aerospike Multi-Site Clustering

The text discusses the implementation of multi-site clustering in Aerospike using strong consistency and rack awareness features. It explains how to construct a multi-site database cluster with full data replication across multiple sites, ensuring continuous operation even during network partitions or site failures without any loss of data. The article also presents an alternative arrangement for two data centers and introduces the concept of a tie breaker node in recent server releases. This feature eliminates the need for operator intervention and reduces hardware usage while maintaining full data replication across multiple sites, making it suitable for building fully resilient distributed Aerospike clusters.
