Resumable Transfer
Full data migration provided by DTS supports table-level and row-level resumable transfer under certain conditions. When a task is paused or restarts unexpectedly, a migrated table will not be migrated again. If relevant conditions are met, DTS resumes the migration from the row with the breakpoint by default.
Incremental data migration provided by DTS supports resumable transfer by recording offsets. When a task is paused or restarts unexpectedly, DTS starts to migrate incremental data from the last recorded offset.
Highly Available Worker Nodes
eSurfing Cloud DTS technically supports dual-node redundant deployment of worker nodes and provides automatic primary/standby failover to ensure high availability (HA). However, during the public preview, DTS does not provide the dual-node HA specification for data synchronization. We plan to release this HA specification in future versions.
