      "text": "> This maintenance release replaces the 1.4.0 release.\n\nRDI’s mission is to help Redis customers sync Redis Enterprise with live data from their slow disk-based databases to:\n\n- Meet the required speed and scale of read queries and provide an excellent and predictable user experience.\n- Save resources and time when building pipelines and coding data transformations.\n- Reduce the total cost of ownership by saving money on expensive database read replicas.\n\nRDI 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.\nIt 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."

You can install on [OpenShift](https://docs.openshift.com/) or other flavours of K8s using Helm.\n\n- Improvements for installation on VMs:\n\t- Installer checks if the OS firewall is enabled on Ubuntu and RHEL.\n\t- Installer verifies DNS resolution from RDI components.\n\t- Installer provides log lines from components that failed during RDI deployment if a problem occurs.\n\t- Improved verification of RDI installation.\n\t- Installer verifies if the RDI database is in use by another instance of RDI.\n\t- Installer checks and warns if any [`iptables`](https://www.netfilter.org/projects/iptables/index.html) rules are set.\n\t- Improved message when RDI tries to connect to its Redis database with invalid TLS keys."
