New feature | Data can be synchronized from a self-managed Oracle database to a PolarDB for MySQL cluster. Compared with a data migration task, a data synchronization task allows you to modify the objects to be synchronized based on your business requirements. | Synchronize data from a self-managed Oracle database to a PolarDB for MySQL cluster |
New feature | Data can be migrated from a MySQL-compatible OceanBase database to an ApsaraDB RDS for MySQL instance or a PolarDB for MySQL cluster in the China (Qingdao) region. This helps you reduce database O&M costs. | |
New feature | Data can be synchronized or migrated from an ApsaraDB RDS for MySQL instance to a Tair (Redis OSS-Compatible) instance in the China (Qingdao) region. This meets your business requirements such as high throughput, low latency, and elastic scaling. | |
Optimized feature | Data can be synchronized or migrated from a Tair (Redis OSS-Compatible) Enhanced Edition instance or a Tair instance of Version 6.0. | |
Optimized feature | PolarDB for MySQL clusters that have SSL encryption enabled are supported in DTS. | |
Optimized feature | Two-way synchronization is supported between PolarDB-X 2.0 Standard Edition instances. | Configure two-way synchronization between PolarDB-X 2.0 instances |
