Redis Data Integration release notes 1.6.2 (March 2025)

Installation on Kubernetes with a Helm chart. Improvements for installation on VMs.

This maintenance release replaces the 1.6.1 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) 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

  • Fix: With an RDI namespace that contains dashes, rdi-metrics-exporter crashes immediately upon startup
  • Fix reported security vulnerabilities
  • Fix: Connection to PostgreSQL from Debezium fails with "could not read SSL key file" when using mTLS

Fixes & Improvements

  • Resolved startup crash in rdi-metrics-exporter Fixed an issue where the exporter would crash on startup if the RDI namespace included dashes (e.g., my-namespace) that are not allowed in prometheus labels.

  • Security Vulnerabilities Patched Addressed the following reported CVEs:

    • CVE-2019-14250
    • CVE-2019-17543
    • CVE-2023-32665
    • CVE-2024-52533
    • CVE-2020-17049
    • CVE-2024-47874

  • Improved mTLS compatibility in collector-initializer DER-formatted keys are now skipped during initialization, resolving a PostgreSQL connection error with Debezium (could not read SSL key file) when using mTLS.

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.
