- ▸ Cluster cohesion failing after restart - Heartbeat takes 90+ seconds to re-establish; clients hit
CLUSTER_KEY_MISMATCHerrors during the gap. - ▸ XDR active-active write conflict - Same key written in both regions within the XDR conflict window; LWW based on system time means you lost the update from the slower clock.
- ▸ Tomb-raider not reclaiming tombstones - Durable-delete tombstones piling up while
stop-writes/high-water-disk-pctblock writes despite plenty of disk headroom.

Aerospike High Availability Solutions
In short: Aerospike high availability involves in-cluster synchronous replication with configurable replication factor, XDR cross-datacenter replication, multi-region deployment, and cluster-aware smart client routing - plus strong-consistency configuration, automatic sub-second failover, and disaster-recovery planning with defined RTO/RPO across single-DC, active-passive, active-active, and hybrid-cloud patterns.
Build resilient Aerospike infrastructure with a 99.999% uptime target. Expert XDR configuration, automatic failover, multi-region deployment, and comprehensive disaster recovery planning for mission-critical real-time applications.

HA Deployment Patterns
Proven deployment patterns for different availability requirements
Single Datacenter HA
High availability within a single datacenter with rack awareness
Architecture:
- 3-5 node cluster minimum
- Replication factor of 2
- Rack-aware data placement
- Load balancer integration
Active-Passive DR
Primary datacenter with standby DR site using XDR
Architecture:
- Primary cluster (active)
- DR cluster (passive)
- XDR unidirectional shipping
- Manual failover procedures
Active-Active Multi-Region
Multiple active datacenters with bidirectional XDR replication
Architecture:
- Multiple active clusters
- Bidirectional XDR
- Conflict resolution policies
- Global traffic routing
Hybrid Cloud HA
On-premises cluster with cloud-based DR site
Architecture:
- On-premises primary cluster
- Cloud DR cluster (AWS/GCP/Azure)
- Secure XDR over VPN
- Automated failover capability
Who uses HA? (Success Stories)
Real-world high availability implementations with measurable results
Challenge:
Needed 99.999% uptime for real-time bidding across 4 global regions with <5ms latency
Solution:
Deployed active-active Aerospike clusters in 4 regions with XDR, smart routing, and automated failover
Results:
- 99.999% uptime achieved
- Zero bid losses from outages
- Sub-millisecond local latency
- Smooth regional failovers
Challenge:
Required strong consistency for in-cluster trading data with near-zero RPO and RTO under 1 minute
Solution:
Implemented strong consistency mode with rack-aware synchronous in-cluster replication plus asynchronous XDR to the DR site and automated failover procedures
Results:
- Zero in-cluster data loss with SC mode
- RTO of 30 seconds achieved
- Regulatory compliance maintained
- Automated DR testing weekly
Challenge:
50M concurrent players requiring session persistence across 3 continents with instant failover
Solution:
Multi-region deployment with XDR, conflict resolution for session data, and global load balancing
Results:
- Zero downtime during updates
- 50M+ concurrent sessions
- <2ms session access latency
- Smooth region failovers
