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. ## Headlines - Installation on [Kubernetes]({{< relref "/integrate/redis-data-integration/installation/install-k8s" >}}) using a [Helm chart](https://helm.sh/docs/). You can install on [OpenShift](https://docs.openshift.com/) or other flavours of K8s using Helm. - Improvements for installation on VMs: - Installer checks if the OS firewall is enabled on Ubuntu and RHEL. - Installer verifies DNS resolution from RDI components. - Installer provides log lines from components that failed during RDI deployment if a problem occurs. - Improved verification of RDI installation. - Installer verifies if the RDI database is in use by another instance of RDI. - Installer checks and warns if any [`iptables`](https://www.netfilter.org/projects/iptables/index.html) rules are set. - Improved message when RDI tries to connect to its Redis database with invalid TLS keys. ## Issues fixed - **RDSC-2802**: Reintroduce checks for DNS resolution and network connectivity from inside a K8s pod. - **RDSC-2804**: RDI installation previously failed if the user specified a non-default HTTPS port. The user can now specify the port correctly. ## 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.
