Frequently Asked Questions
Common questions about Aerospike high availability solutions
What uptime SLA can Aerospike achieve?
With proper configuration, Aerospike can achieve 99.999% uptime (five nines), which translates to less than 5.26 minutes of downtime per year. This is achieved through automatic data replication, cluster-aware clients, seamless failover mechanisms, and proper capacity planning.
How does Aerospike XDR work for disaster recovery?
Aerospike XDR (Cross-Datacenter Replication) asynchronously replicates data between geographically distributed clusters. It supports active-active configurations, customizable conflict resolution policies (based on generation, last-update-time, or custom logic), and can maintain data consistency across multiple regions for disaster recovery and global data distribution.
Can Aerospike maintain sub-millisecond latency with HA?
Yes, Aerospike's architecture is designed to maintain sub-millisecond read and write latency even with replication enabled. The cluster-aware smart client routes requests optimally to the node containing the data, and data replication happens synchronously within the cluster without significantly impacting response times.
What is the difference between replication and XDR?
Replication is synchronous data copying within a single cluster for fault tolerance. XDR (Cross-Datacenter Replication) is asynchronous replication between separate clusters, typically in different datacenters or regions, designed for disaster recovery and global data distribution.
How do you handle split-brain scenarios?
Aerospike uses a roster-based approach with strong consistency mode to prevent split-brain scenarios. The cluster only accepts writes when a majority of roster nodes are available. For eventual consistency mode, conflict resolution policies determine which write wins based on generation count or timestamp.
What is the recommended replication factor?
For production environments, we recommend a replication factor of 2 as the minimum, which provides tolerance for single node failures. For mission-critical applications, a replication factor of 3 provides protection against two simultaneous node failures while maintaining excellent performance.
How do you test disaster recovery procedures?
We implement regular DR testing including planned failover drills, recovery time measurements, procedure validation, and gap identification. This includes both controlled failovers and chaos engineering practices to ensure your systems can handle real-world failure scenarios.
