> This is a GA version of Redis Data Integration (RDI) that improves the installation of RDI.

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](https://redis.io/docs/latest/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.

## 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.
