Tair (Redis OSS-compatible)
Category | Feature | Description | References |
Architecture | Master-replica architecture | A standard master-replica instance consists of one master node and one replica node. | |
Read/write splitting ️architecture | You can enable the read/write splitting feature. A read/write splitting instance consists of one master node and up to nine read replicas. You can change the number of read replicas at any time. | ||
Cluster architecture | Tair (Redis OSS-compatible) supports the native Redis Cluster architecture and the cluster architecture in proxy mode. A cluster instance can contain 2 to 256 shards, with the memory of each shard ranging from 1 GB to 64 GB. The total memory capacity of shards ranges from 2 GB to 16 TB. | ||
Standalone architecture | A standalone instance consists of only one node and its price is 50% that of a standard master-replica instance. The standalone architecture does not support backup and restoration, ensure data reliability, or provide service level agreement (SLA) guarantee. It is suitable for cache-only scenarios. | - | |
Specification and architecture change | Configuration upgrade | You can upgrade the configurations of an instance by expanding the storage capacity of individual shards and increasing the number of shards. | |
Configuration downgrade | You can downgrade the configurations of an instance by reducing the storage capacity of individual shards and decreasing the number of shards. | ||
Cross-architecture configuration change | Tair (Redis OSS-compatible) allows you to seamlessly migrate between the standalone, master-replica, read/write splitting, and cluster architectures without altering application code. | ||
Version compatibility | Compatibility with Redis 4.0, 5.0, 6.0, and 7.0 | Tair (Redis OSS-compatible) is compatible with Redis 4.0, 5.0, 6.0, and 7.0. | New features and compatibility changes of major versions of Redis Open-Source Edition |
Compatibility with Memcache | Tair (Redis OSS-compatible) is compatible with the Memcache API. | ||
Security | Dynamic masking of commands | High-risk commands can be dynamically disabled without the need to restart an instance. | |
Multi-account management | This feature allows you to create multiple accounts and grant permissions to each account. | ||
IP address-based access control | This feature supports dynamic access control based on IP address whitelists. | ||
Associated security groups | Security groups can be used to dynamically control access. | ||
Write operation audit | This feature enables the logging of each write request, capturing details such as the exact time of the operation, client IP address, user account, and associated keys. This information is essential for analyzing data anomalies. | ||
Transparent data encryption (TDE) | TDE is supported. | ||
IP whitelist template | An IP whitelist template can be associated with multiple instances to easily maintain the IP address whitelists of multiple instances. | ||
Transport Layer Security (TLS) and Secure Sockets Layer (SSL) | TLS and SSL encryption is supported. | ||
Recycle bin | The recycle bin feature is supported. | ||
Observability | Multiple metrics | Tair (Redis OSS-compatible) supports multiple metrics, such as Memory, Stats, CPU, and Keyspace. This allows you to monitor the status of instances from multiple perspectives. | |
Latency insights | This feature offers a multi-dimensional, precise display of latency statistics for various Redis commands and special events to improve the efficiency of database troubleshooting. | ||
Analysis of large keys and hotkeys | Tair (Redis OSS-compatible) provides both offline analysis of large keys across the entire dataset and real-time analysis of requested keys. This allows for quick identification of large keys and hotkeys. | ||
Slow query log analysis | This feature allows you to view and analyze slow query logs, giving you clues about how to optimize requests. | ||
Lifecycle management | Lifecycle management | This feature allows you to manage an instance throughout its lifecycle, including creating, releasing or unsubscribing from, changing the billing method of, upgrading the version of, and restarting the instance. | |
Backup and restoration | Manual backup | Manual backup is supported. Up to 15 backup data copies can be retained per day. | |
Automatic backup | The system automatically performs backups based on the backup policy that you define. | ||
Full data restoration | Data can be restored from a backup set to a new instance. | ||
Data flashback | This feature allows you to restore an entire instance or specific keys of the instance to a point in time accurate to the second. | ||
High availability | Automatic and manual master-replica switchover | Tair (Redis OSS-compatible) supports both automatic high-availability failover and manual master-replica switchover. This facilitates real-time disaster recovery drills. | Manually switch workloads from a master node to a replica node |
Restart or rebuild of proxy nodes | Tair (Redis OSS-compatible) allows you to manually restart or rebuild proxy nodes. This facilitates real-time disaster recovery drills and allows for proactive O&M in the event of service anomalies or elevated latency. | ||
Connection management | Virtual private cloud (VPC) or vSwitch change | The VPC or vSwitch of an instance can be changed. | |
Applying for or releasing public endpoints | By default, Tair (Redis OSS-compatible) provides only VPC endpoints. If you want to connect to a Tair (Redis OSS-compatible) instance over the Internet, you can apply for a public endpoint for the instance. | ||
Enabling or releasing private endpoints | Tair (Redis OSS-compatible) allows you to enable the direct connection mode, providing compatibility with the native Redis Cluster protocol. | ||
Scalability | Manual and automatic activation of bandwidth plans | Tair (Redis OSS-compatible) provides the flexibility to manually or dynamically increase the bandwidth of an instance without adjusting the instance type to easily cope with traffic spikes. | |
Imperceptible scaling | Instance scaling is completely imperceptible to clients. It does not cause service interruptions or put the instance into a read-only state. This feature meets the requirements for on-demand elastic resource scaling. | ||
Performance optimization | Proxy query cache | After proxy query cache is enabled, proxy nodes cache requests for hotkeys and their associated query results. | |
Log management | Audit log | Tair (Redis OSS-compatible) allows you to enable the audit log feature and query and download audit logs. | |
Query of slow query logs | Tair (Redis OSS-compatible) allows you to query the slow query logs of data nodes and proxy nodes. | ||
Query of active logs | Tair (Redis OSS-compatible) allows you to query the active logs of an instance. | ||
Event management | Change of the scheduled maintenance window of O&M events | Tair (Redis OSS-compatible) allows you to schedule O&M events to be performed during the maintenance window and change the maintenance window based on your business requirements. | |
Query of O&M event progress | The progress of O&M events can be queried. | ||
Parameter management | Instance parameter configuration | Instance parameters can be configured. | |
Parameter query | The parameter list can be queried. | Parameters that can be configured for Redis Open-Source Edition instances |
