Features
Architectures for Various Availability Requirements
ApsaraDB for OceanBase can be deployed across zones and regions. If a fault occurs, your workloads are switched to a healthy zone based on the specified priority. You can select zones based on your business requirements.
Zone-Disaster Recovery
You can deploy ApsaraDB for OceanBase across three zones in a single region. In this scenario, you can achieve a Recovery Point Objective (RPO) of zero and a Recovery Time Objective (RTO) of less than 30 seconds. Automatic failover is triggered when a fault occurs. This deployment solution helps you ensure service continuity when a hardware fault or zone disaster occurs.
Geo-Disaster Recovery
You can deploy ApsaraDB for OceanBase across five zones in three regions. In this scenario, you can achieve an RPO of zero and an RTO of less than 30 seconds. Automatic failover is triggered when a fault occurs. This deployment solution helps you ensure service continuity when a hardware fault, zone disaster, or geo-disaster occurs.
Multitenancy to Meet Business Requirements at Minimal Cost
ApsaraDB for OceanBase allows you to select the database engine for a cluster.
Oracle
ApsaraDB for OceanBase is compatible with the Oracle syntax and stored procedures. Oracle-based applications can be migrated seamlessly or with minimal modifications.
MySQL
ApsaraDB for OceanBase is compatible with the MySQL 5.6 syntax and client. You can use ApsaraDB for OceanBase the same way as you use MySQL. ApsaraDB for OceanBase provides financial-grade database capabilities such as scalability and high availability.
Financial-grade Features
ApsaraDB for OceanBase provides financial-grade features such as recycle bin and flashback query to ensure service availability and fault tolerance.
Flashback Query
ApsaraDB for OceanBase provides the flashback query feature for DML-related misoperations. This feature allows you to query previous data values or restore a table or row to a previous time point.
Recycle bin
ApsaraDB for OceanBase provides the recycle bin feature for DDL-related misoperations. This feature allows you to restore data in case you perform the DROP TABLE or DROP DATABASE operation.
Execution Plan Evolution
Only verified execution plans can be enabled. When a new plan is available for the target SQL statement due to various reasons such as changes in statistics, the new plan is not immediately enabled. The new plan must be verified by a small volume of data inside the OBServer and must have better performance than previous plans before it can be enabled.

High-performance database
Outstanding performance during TPC-C benchmark test
All database kernel developers want to take on the challenge of the TPC-C benchmark. However, it is never easy to address all of the challenges that are presented in complex benchmarks like TPC-C. This also happened to be the very first time that ApsaraDB for OceanBase took on the TPC-C benchmark. To beat the TPC-C benchmark test, the research and development team of ApsaraDB for OceanBase prepared for more than a year.
High-availability database
High availability and disaster recovery
The primary requirement for high availability of databases is automatic failover with zero data loss. If automatic failover is enabled, services can be recovered in the shortest time. Recovery Time Objective (RTO) is used to measure the recovery time. Recovery Point Objective (RPO) is the metric for data loss after service recovery. RTO and RPO are important metrics to evaluate a high availability solution.
High-throughput database

High Availability and Disaster Recovery
Unattended and Self-Adaptive Disaster Recovery
ApsaraDB for OceanBase provides a customizable solution for high availability and disaster recovery. You can deploy ApsaraDB for OceanBase based on the application scenarios and your business requirements for zones and regions. You can implement financial-grade high availability by using basic hardware.
Flexible High Availability
ApsaraDB for OceanBase can be deployed across zones and regions. It allows you to customize the disaster recovery capability based on your business scenarios. ApsaraDB for OceanBase uses the Paxos protocol to ensure the consistency of data replicas that are deployed across different regions or zones. If a zone or region fails, ApsaraDB for OceanBase switches your workloads to a healthy node where a data replica resides.
High Availability Across Regions and Unit-based Redundancy
If you deploy ApsaraDB for OceanBase across regions, you can deploy the master nodes of different tenants in different regions. With OBProxy, you can modularize your business systems and realize high availability across regions. Among users of ApsaraDB for OceanBase, MYbank and Paytm adopt similar architectures. Module-based distribution and redundancy provide support for capacity scaling and region-level disaster recovery.
Asynchronous Replication
ApsaraDB for OceanBase asynchronously replicates data from the active cluster to the standby cluster. The active and standby clusters are independent of each other. This prevents failures from being transferred to the standby cluster when the active cluster encounters an error.
Scale-out
Similar Experience to Using Standalone Databases
ApsaraDB for OceanBase is a native distributed relational database that can be used in the same way as a standalone relational database. You can improve the computing and storage capacity by increasing the number of nodes. In a distributed system or sharded architecture, global indexes and global consistency are usually compromised. Therefore, it requires extra costs to address these needs. To solve this issue, ApsaraDB for OceanBase provides capabilities such as snapshot isolation levels and multi-version concurrency control (MVCC) by using global timestamps and global indexes.
Distributed Transactions
In ApsaraDB for OceanBase, a table is split into many small partitions and distributed across multiple nodes for storage based on a specific policy. All transactions are executed as distributed transactions. Global timestamps are used to ensure that the distributed transactions in an ApsaraDB for OceanBase cluster meet the requirements of atomicity, consistency, isolation, and durability (ACID) and transaction isolation levels.
Global Indexes
ApsaraDB for OceanBase supports partial and global indexes within a partition. Partial indexes have lower maintenance costs and higher execution efficiency. Global indexes can help avoid partition scans and table scans that are required in traditional sharded architectures. Global uniqueness constraints can help avoid complex architectures introduced by various uniqueness requirements. ApsaraDB for OceanBase optimizes the performance of global indexes by using the two-phase commit mechanism and non-covered queries. The optimization ensures that global indexes can meet the requirements of most core scenarios.
Global Consistency
Transaction Integrity Across Databases
ApsaraDB for OceanBase provides a global consistency solution that does not rely on specific hardware. ApsaraDB for OceanBase provides capabilities such as snapshot isolation levels and multi-version concurrency control (MVCC) to ensure global consistency of snapshot versions.
Traditional architectures for table sharding and database sharding do not support global and unified snapshot management.
Transaction Integrity
ApsaraDB for OceanBase uses Global Timestamp Service (GTS) to ensure consistency of snapshot versions. All transactions obtain snapshot versions from GTS regardless of the source servers. The version numbers of snapshots increase over time. The timestamps of all snapshots are consistent with the real world chronological order. ApsaraDB for OceanBase assigns global timestamps by tenant.
