Welcome to the February release of ClusterControl v2.3.1. This update introduces new features primarily for PostgreSQL and Valkey:

Features

PostgreSQL

  • Support for PostgreSQL bi-directional logical replication.
    • Supported with PostgreSQL version 16:
      • PostgreSQL bi-directional replication allows multiple database instances to independently handle read and write operations. Changes made on any node are synchronized with other participating nodes, ensuring that data is eventually consistent across the system. This setup enables multiple-way synchronization, allowing each node to act as both a sender and recipient of updates. Conflict detection mechanisms are in place to resolve conflicting updates based on predetermined rules. The system operates asynchronously, meaning changes may not be instantly reflected across all nodes but will synchronize over time. This replication method enhances high availability, allowing nodes to continue processing requests even if others fail, minimizing downtime. It is particularly useful for geographically distributed databases, as each region can handle its own updates and synchronize with others.
    • Deploy a new PostgreSQL logical replication cluster:
      • Easily set up and configure PostgreSQL logical replication clusters from scratch.
    • Setup/configure PostgreSQL logical replication between two existing PostgreSQL clusters:
      • Seamlessly establish logical replication between two existing PostgreSQL clusters.
    • Publications and subscriptions management:
      • Manage publications and subscriptions to control which data is replicated and to which nodes.
      • Alarms when publication/subscription link is disabled/broken.

Support for Valkey Sentinel

  • Valkey Sentinel is an alternative to Redis Sentinel which is a high-availability (HA) tool that comes as part of Redis, designed to monitor Redis instances, automatically handle failovers, and provide notifications about the system’s health. It’s a key component for deploying Redis in environments requiring redundancy and resilience.

  • Use Valkey Sentinel 8.0 with the same feature set that we support for Redis Sentinel.

Misc

  • New Cluster Load overview dashboards for Redis, Valkey, and MongoDB.
