      "text": "> This maintenance release replaces the 1.6.1 release.\n\nRDI’s mission is to help Redis customers sync Redis Enterprise with live data from their slow disk-based databases to:\n\n- Meet the required speed and scale of read queries and provide an excellent and predictable user experience.\n- Save resources and time when building pipelines and coding data transformations.\n- Reduce the total cost of ownership by saving money on expensive database read replicas.\n\nRDI keeps the Redis cache up to date with changes in the primary database, using a [_Change Data Capture (CDC)_](https://en.wikipedia.org/wiki/Change_data_capture) mechanism.\nIt also lets you _transform_ the data from relational tables into convenient and fast data structures that match your app's requirements. You specify the transformations using a configuration system, so no coding is required."
