Two-way data synchronization is a key feature that distinguishes Data Transmission Service (DTS) from Redis-shake. DTS is designed to support complex data synchronization scenarios, such as bi-directional synchronization between data sources. This capability enables changes made in one database to be reflected in another, and vice versa, ensuring that both databases remain consistent with each other. This is particularly useful in environments where data needs to be mirrored or where applications require real-time data updates across multiple locations.

In contrast, Redis-shake is primarily focused on one-way data replication, making it suitable for simple migration tasks rather than bidirectional synchronization. Its design does not support the complexities involved in maintaining consistency between two separate databases in both directions, which is a significant aspect of DTS. Additionally, DTS includes features for migration management and data visualization, further enhancing its utility in dealing with complex data scenarios, unlike Redis-shake, which lacks these advanced functionalities.
