August 2024
Category | Feature | References |
New feature | Migrate data from a MySQL-compatible OceanBase database to a Lindorm instance to help reduce database O&M costs. | Migrate data from a MySQL-compatible OceanBase database to a Lindorm instance |
Optimized feature | If a self-managed MongoDB database is used as the source or destination database in a data synchronization or migration task configured in the Data Transmission Service (DTS) console, you can specify multiple endpoints for the MongoDB database to enhance the stability of data synchronization or migration. | |
Optimized feature | Add additional columns to a destination table when the Database Type of the destination database of a data synchronization or migration task is Kafka. | |
Optimized feature | Configure a DTS task across Alibaba Cloud accounts when the Database Type of the destination database of the DTS task is Tair/Redis and the Access Method is Alibaba Cloud Instance. | |

July 2024
Category | Feature | References |
New feature | Synchronize or migrate data from an ApsaraDB RDS for MySQL instance to a Lindorm instance. | |
New feature | Synchronize or migrate data from an ApsaraDB for MongoDB instance to an AnalyticDB for MySQL V3.0 cluster. | |
New feature | Synchronize or migrate data from an ApsaraDB for MongoDB instance to an AnalyticDB for PostgreSQL instance. | |
New feature | DTS provides the Exactly-Once write feature for two-way data synchronization instances. This feature allows you to synchronize full and incremental data from source tables that do not have primary keys or UNIQUE constraints to destination tables. | Synchronize tables without primary keys or UNIQUE constraints |
New feature | Configure two-way data synchronization between ApsaraDB RDS for MySQL instances and between PolarDB for MySQL clusters, and configure independent conflict resolution policies for incremental synchronization tasks. | |
New feature | Add Polling and querying CDC instances for incremental synchronization in SQL Server Incremental Synchronization Mode to synchronize or migrate incremental data from source SQL Server database. | |
New instance types | Serverless instances provide scalable resources to meet changing business requirements. This avoids resource waste and reduces O&M costs. | |
Optimized feature | Support SQL Server database and ApsaraDB for MongoDB instance that have SSL encryption enabled. |
June 2024
Category | Feature | References |
New feature | Add additional columns to a destination table when you create a data synchronization or migration instance between MySQL, PolarDB for MySQL or MariaDB databases. | |
Optimized feature | Support ApsaraDB RDS for PostgreSQL database that has SSL encryption enabled. |
April 2024
Category | Feature | References |
New feature | Synchronize or migrate accounts of the source database and their passwords and permissions to the destination database only between MySQL databases, from MySQL databases to PolarDB for MySQL clusters, or between PolarDB for MySQL clusters. | |
Optimized feature | Support destination PolarDB for MySQL cluster instances to replicate data across Alibaba Cloud accounts. |
March 2024
Category | Feature | References |
New feature | PostgreSQL 16 is supported for data synchronization or migration scenarios. | |
New feature | Create a reverse instance for incremental data synchronization for one-way data synchronization between ApsaraDB RDS for MySQL instances. | |
New feature | Create a DTS task in which the source database is a secondary node of an ApsaraDB RDS for MySQL Cluster Edition instance. |
February 2024
Category | Feature | References |
New feature | Configure Tair (Enterprise Edition) ESSD-based instances as the source database. |
January 2024
Category | Feature | References |
New feature | SQL Server 2022 and ApsaraDB for Redis 7.0 are supported for data synchronization or migration scenarios. | |
Optimized feature | When the source self-managed MongoDB database is connected to DTS by using Express Connect, VPN Gateway, or Smart Access Gateway, Public IP Address, or Cloud Enterprise Network (CEN), you can select the Architecture. If the source self-managed MongoDB database uses the sharded cluster architecture, you can set the Architecture to Sharded Cluster. This way, you do not need to create a task for each shard node. | |
Optimized feature | When you create a DTS task to synchronize or migrate data from a MySQL database to an ApsaraMQ for Kafka instance, the Access Method parameter can be set to Alibaba Cloud Instance for the ApsaraMQ for Kafka instance. |
