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.
