Compatibility and support matrix
The following table shows the compatibility and support matrix between the Alauda Cache Service for Redis OSS and ACP versions.
| Alauda Cache Service for Redis OSS Version | Redis Versions | ACP Version |
|---|---|---|
| v4.1.0 | 5.0.14, 6.0.20, 7.2.10 | v4.1 |
| v4.0.x | 5.0.14, 6.0.20, 7.2.x | v4.0 |
v4.1.0
New and Optimized Features
Redis Disaster Recovery Support (Alpha)
Support enabling disaster recovery functionality for Redis instances, including:
- Data synchronization configuration in disaster recovery scenarios.
- Monitoring and alert settings.
- Failover.
- Source-end information management.
Switching access methods
Support switching between access methods for instances in the Data Services view, including switching between intra-cluster and inter-cluster access methods.
Fixed Issues
- Previously, when creating a Redis instance in the Data Services view, if the PVC capacity filled in on the UI form was less than the memory capacity, it would cause the instance creation form submission to fail.
This has been fixed in Alauda Cache Service for Redis OSS v4.1.0.
Known Issues
- When upgrading a Redis Sentinel instance from v5 to v7, occasional brain split incidents may occur, potentially leading to data loss.
Solution: Back up the Redis instance data before performing a cross-version upgrade.
v4.0.0
New and Optimized Features
Component-Platform Decoupling
Alauda Cache Services for Redis OSS's lifecycle has been decoupled from platform's, which means when customer needs a certain feature or a bug fix, Redis team can release immediately instead of waiting for the platform release together.
Real-Time Logs on Component Details Page
The logs on Redis details page have been replaced with real-time logs that update instantly, facilitating troubleshooting and issue analysis.
External Access via LoadBalancer for Redis
LoadBalancer access is now supported for Redis. When creating an instance, users can choose to expose services externally through a LoadBalancer-type Service.
Compare to NodePort, LoadBalancer provides better high availability, performance, and export standard port. It is recommended to use the LoadBalancer method in production environments.
Limitations
When using LoadBalancer, ensure that the cluster has available external address pools. We recommend using MetalLB to create external address pools for the cluster.
Fixed Issues
- Previously, during Redis instance upgrades from v6.0 to v7.2, infrastructure instability could (in rare cases) lead to data loss. This issue has been resolved in Alauda Cache Service for Redis OSS v4.
Known Issues
No issues in this release.
