InnoDB engine
Note:
As the database audit feature is being refactored and upgraded, it is not available for newly purchased instances during this period.
Instance Architecture | Definition | Node | Feature |
Standard Edition (one source and one replica) | Each shard provides a high-availability architecture based on source/replica active-active deployment. | Two nodes: One source node and one replica node | Supports read-only replicas. In the 1-source-1-replica architecture, the read-only replica feature can only be used for low-load read-only tasks. Avoid high-load tasks such as large transactions, as they affect the backup tasks and availability of the replica server. Automatic node failover. Default sampling granularity for monitoring: Once every 5 minutes. Maximum backup time: 7 days. Operation log backup time: 7 days. Supports database audit where audit logs can be retained for 15 days and an unlimited number of rules which can be configured. |
| Standard Edition (one source and two replicas) | Each shard provides a high-availability architecture based on source/replica multi-site active-active deployment. | Three nodes: One source node and two replica nodes |
Finance Edition (one source and one replica) | Each shard provides a high-availability architecture based on source/replica active-active deployment. | Two nodes: One source node and one replica node | Supports other deployment schemes. To use other schemes, contact your Tencent Cloud sale rep. Supports read-only replicas and implements intelligent load scheduling for read-only replicas. Automatic node failover. Default sampling granularity for monitoring: Once every 1 minute. Operation log backup time: 60 days by default (1 year for archive storage). Supports database audit where audit logs can be retained for 15 days. Provides assistance for regulatory compliance. |
| Finance Edition (one source and two replicas) | Each shard provides a high-availability architecture based on source/replica multi-site active-active deployment. | Three nodes: One source node and two replica nodes |
TDStore engine
In the beta test phase, the TDStore engine adopts a high-availability architecture of three nodes: one source node and two replica nodes.
