Overview

Data Transmission Service helps you migrate data between data storage types, such as relational database, NoSQL, and OLAP. The service supports homogeneous migrations as well as heterogeneous migration between different data storage types. Data Transmission Service also can be used for continuous data replication with high availability. In addition, Data Transmission Service can help you subscribe to the change data function of ApsaraDB for RDS. With Data Transmission Service, you can easily implement scenarios such as data migration, remote real time data backup, real time data integration and cache refresh.

Benefits

• High Performance The rate of migrating existing data can be up to 70 MB/s The rate of replicating change data can be up to 30,000+ records per second
• Real-Time Data Replication Data Transmission Service supports real-time data synchronization from one RDS database to another RDS database You can modify the synchronization object during the synchronization process
• Simple-to-Use You can begin a database migration with just a few clicks from the Data Transmission Service Management Console You can monitor and manage your tasks in the management console anytime, anywhere
• Reliable Data Transmission Service continually monitors the source and target databases, when the connection changes, Data Transmission Service dynamically modifies the connection in order to optimize performance

Features

Zero Downtime

Data Transmission Service helps you migrate data with virtually no downtime. All data changes to the source database that occurs during the migration is continuously replicated to the target, allowing the source database to remain fully operational during the migration process. After the database migration is complete, the target database will remain synchronized with the source for if you choose, allowing you to switch over the database at a convenient time.

Supports Most Widely Used Databases

Data Transmission Service can migrate your data to and from most of the widely used commercial and open source databases. It supports homogeneous migrations such as MySQL to MySQL, as well as heterogeneous migrations between different database platforms, such as Oracle to MySQL. Migrations can be from on-premises databases to RDS or ECS, databases running on ECS to RDS, or vice versa, as well as from one RDS database to another RDS database. Data Transmission Service supports multiple transmission modes, such as data migration, real time data replication, and change data subscription.

Data Migration

• Zero Downtime All data changes to the source database that occur during the migration are continuously replicated to the target, allowing the source database to be fully operational during the migration process. After completion of the database migration, the target database will remain synchronized with the source if you choose, allowing you to switch over the database at a convenient time.
• Supports Most Widely Used Databases Data Transmission Service supports homogeneous migration such as MySQL to MySQL, SQL Server to SQL Server, as well as heterogeneous migration such as Oracle to MySQL. Data Transmission Service supports heterogeneous migrations between different database platforms. Migrations can be from on-premises databases to ApsaraDB for RDS or Alibaba Cloud ECS, databases running on ECS to RDS, or vice versa, as well as from one RDS database to another RDS database.

Real-Time Change Data Subscription

Data Transmission Service supports real-time subscribing of change data of RDS. You can modify the subscription object after subscription instance created.

Automatic Monitoring

Provides crucial instance information like replication delay, transmission status, and consumption delay in real time so that you can monitor and protect business critical applications. Try out over 40 products for free.

Simple-to-Use

Data Transmission Service manages all the complexities of the migration process including automatically replicating data changes that occur in the source database during the migration process.

Reliable

Data Transmission Service continually monitors the source and target databases, when the connection changes, Data Transmission Service dynamically modifies the connection in order to optimize performance.

High Performance

Data Transmission Service's high performance supports replication in parallel, and supports multiple network optimization features, such as data compression and packet retransmission.
