What is Azure HorizonDB?
Azure HorizonDB is a distributed SQL database designed for applications that need to operate across multiple regions with low latency. It extends PostgreSQL compatibility with built-in global distribution, enabling data to be replicated and accessed from locations close to users.
The service is currently in preview and targets workloads that require both SQL capabilities and global scale, such as SaaS platforms serving customers worldwide or applications that need active-active deployments across continents.
Core Features
- PostgreSQL compatible: Use existing PostgreSQL tools and drivers
- Global distribution: Automatic data replication across Azure regions
- Low-latency reads: Serve data from the nearest replica
- Geo-partitioning: Control where specific data resides for compliance
- Automatic failover: Continue operations if a region becomes unavailable
Typical Use Cases
HorizonDB is suited for applications with a global user base that need consistent, low-latency access to data. Common scenarios include multi-tenant SaaS platforms, global e-commerce sites, and applications that must keep data in specific jurisdictions while providing worldwide access.
Benefits
- Familiar PostgreSQL interface reduces learning curve
- Built-in replication eliminates custom sync logic
- Regional compliance through data placement controls
- Managed service reduces operational overhead
Frequently Asked Questions
How does HorizonDB differ from Cosmos DB?
Cosmos DB is a multi-model database optimized for key-value and document workloads. HorizonDB provides a PostgreSQL-compatible relational experience with SQL support, making it suitable for applications that need traditional relational features with global distribution.
Is HorizonDB production-ready?
HorizonDB is currently in preview. Production workloads should wait for general availability, which will include finalized SLAs and pricing.
Can I migrate from Azure Database for PostgreSQL?
The PostgreSQL compatibility is designed to simplify migration. However, distributed features may require schema considerations like partition keys. Migration tooling and guidance will be available with GA.
What regions are available during preview?
Check Azure documentation for current preview region availability. Additional regions will be added as the service approaches general availability.
