Features

• Kubernetes Operators - Functions as a Kubernetes operator that manages the entire database lifecycle using custom resource definitions.
• Backup & Recovery - Provides physical backup and recovery capabilities using snapshots stored in cloud object storage.
• Database Orchestration - Manages the lifecycle, scaling, and recovery of PostgreSQL clusters through declarative Kubernetes manifests.
• Database Replication - Uses streaming and file-based physical replication to keep standby replicas synchronized with the primary node.
• PostgreSQL Administration Tools - Provides utilities for performing rolling updates, major version upgrades, and read-replica scaling.
• Cluster Lifecycle Management - Automates the provisioning and operational lifecycle of PostgreSQL database clusters.
• PostgreSQL Kubernetes Administration - Provides a native Kubernetes orchestration layer for the complete administration of PostgreSQL database clusters.
• Primary-Replica Replication - Utilizes streaming physical replication to synchronize data from the primary node to standby replicas.
• Point-in-Time Recovery - Enables restoring database clusters to a specific timestamp via continuous backups to object stores.
• Database Lifecycle Management - Automates the full operational lifecycle of database clusters, including deployment, scaling, and failover.
• Database High Availability - Ensures continuous service availability through automated failover and primary election in database clusters.
• Declarative Configuration Models - Uses a declarative configuration model to define and reconcile the desired state of database clusters.
• Automated Master Failovers - Implements automated primary election and reconfiguration to ensure high availability during node failures.
• Declarative Configuration - Manages database users, roles, and system settings through structured declarative manifests.
• Encrypted Connections - Implements encrypted database connections using SSL/TLS and integration with external certificate managers.
• Database Version Migrations - Executes major database version upgrades using either offline in-place updates or online migrations via logical replication.
• Scaling Orchestrators - Automatically scales the number of standby replicas by provisioning necessary storage and replication settings.
• Traffic Routing - Routes read-write and read-only traffic to different endpoints based on the database node role.
• Cluster Scaling Orchestrators - Dynamically adjusts the number of database instances to scale capacity based on workload requirements.
• Storage Volume Orchestration - Orchestrates persistent storage volume claims to ensure data persistence during pod migrations or updates.
• Distributed Database Deployment - Enables the deployment of replica clusters across multiple environments for hybrid or multi-cloud distribution.
• Rolling Update Orchestrators - Orchestrates rolling updates of database images by updating replicas first and performing a controlled switchover.
• Version Upgrades - Supports both offline in-place major upgrades and online migrations using logical replication.
• Network Encryption - Encrypts in-transit network traffic using certificates and supports both auto-generated and external credentials.
• Cluster Health Monitoring - Exposes database and operator health metrics for integration with external observability tools.
• Database Performance Monitoring - Exports PostgreSQL performance metrics and telemetry for integration with external observability tools.
• Metrics Exporters - Collects database telemetry via a built-in exporter for integration into monitoring pipelines.
• Service Alerting Configurations - Defines alert conditions and monitoring rules to notify administrators when performance thresholds are crossed.
• Kubernetes Operators - Comprehensive platform for managing PostgreSQL in Kubernetes.
