+To allow RDI to access the Spanner instance, you'll need to create a service account with the

In this case RDI will assume the [service account is assigned to the GKE cluster](https://cloud.google.com/kubernetes-engine/docs/how-to/workload-identity#enable_on_clusters_and_node_pools). Alternatively, you can provide the

+
+RDI’s mission is to help Redis customers sync Redis Enterprise with live data from their slow disk-based databases to:
+
+- Meet the required speed and scale of read queries and provide an excellent and predictable user experience.
+- Save resources and time when building pipelines and coding data transformations.
+- Reduce the total cost of ownership by saving money on expensive database read replicas.
+
+RDI 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.
+It 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.
+
+## What's New in 1.14.1
+
+- Support for Google Cloud Workload Identity authentication when a service account is assigned to the GKE cluster
+- Fixed RDI API job validation that was incorrectly failing when schemas are not explicitly specified in source configuration, even though the configuration was valid
+
+## Limitations
+
+RDI can write data to a Redis Active-Active database. However, it doesn't support writing data to two or more Active-Active replicas. Writing data from RDI to several Active-Active replicas could easily harm data integrity as RDI is not synchronous with the source database commits.
