Stolon
Stolon is a cloud native database manager and orchestrator for PostgreSQL. It functions as a high availability manager designed to automate failover, replication, and cluster management in distributed environments.
The system coordinates synchronous and asynchronous data mirroring and uses a service discovery mechanism to dynamically detect database node addresses. It routes client traffic to the current primary instance through a proxy to maintain application access during role switches.
The project covers disaster recovery through point-in-time recovery and the maintenance of multi-site standby clusters. It also includes capabilities for securing database connections via encryption and automating the detection of process address changes within the network.
Features
- Database Orchestrators - Functions as a cloud-native manager that orchestrates PostgreSQL deployments with dynamic networking and automated recovery.
- Database High Availability - Coordinates database nodes to ensure continuous service availability through automated failover and primary role election.
- WAL-Based Standby Replication - Maintains standby nodes by continuously transmitting real-time write-ahead log records from the primary instance.
- Database Replication - Configures synchronous or asynchronous data mirroring across multiple storage nodes to ensure high availability.
- Real-Time Data Replication - Synchronizes standby instances with the primary node by streaming data changes in real time.
- PostgreSQL Cluster Management Platforms - Provides a comprehensive platform for the deployment and administration of PostgreSQL clusters with coordinated data mirroring.
- Database Orchestration - Deploys and scales PostgreSQL instances across dynamic networks with automated service discovery and routing.
- Cluster Discovery Services - Dynamically identifies and registers database nodes within a network to route clients to the current primary.
- Registry-Based Service Discovery - Uses an external key-value store as a registry to track and resolve the current primary node address.
- Dynamic Service Discovery - Dynamically detects process address changes and reconfigures the cluster to eliminate manual network updates.
- Traffic Routing - Directs client network traffic to the active primary node through a proxy to decouple applications from database topology.
- Database Traffic Routing - Routes database read and write requests across distributed nodes to ensure clients reach the active primary.
- Node Health-Check Failover - Provides automated node health monitoring and failover switching to standby instances when the primary becomes unavailable.
- Disaster Recovery Workflows - Provides automated workflows for point-in-time recovery and standby cluster maintenance to prevent data loss.
- Multi-Site Standby Clusters - Supports cascading data from a primary cluster to remote standby clusters for disaster recovery and geographic redundancy.
- Point-in-Time Recovery - Implements mechanisms to restore database states to specific historical moments by replaying archived write-ahead logs.
- Multi-Site Standby Management - Deploys and maintains secondary clusters for multi-site replication to facilitate migrations and reduce update downtime.
- Dynamic Service Discovery - Implements a dynamic service discovery mechanism to detect database node addresses and route traffic to the active primary.
- Database Systems - Cloud-native high availability solution for PostgreSQL.
- High Availability - High availability management with Kubernetes and consensus integration.
- High Availability and Scaling - Cloud-native manager for PostgreSQL high availability.
