Improvements for installation on VMs. +linkTitle: 1.4.3 (December 2024) +toc: 'true' +weight: 994 +--- + +> This maintenance release replaces the 1.4.2 release. + +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-2963**: Helm chart `rdiSysSecret` does not create an empty secret if you are not using a password. +- **RDSC-2729**: Use Debezium Server 2.7.3 and remove Prometheus. +- **RDSC-2333**: Ensure the installer creates the context file correctly. +- **RDSC-2806**: Remove incorrectly created deployment. +- **RDSC-2729**: Fix `processors` `null` instead of `{}`. +- **RDSC-2905**: Fix DNS check with multiple IP addresses. +- **RDSC-2845**: RDI Helm chart release is set with `tag: 0.0.0`, but this should be the current release. + +## 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.
