Amazon RDS for Oracle: Redo Transport Compression Now

⚙️ Amazon RDS for Oracle now supports Redo Transport Compression, which compresses redo data before it is transmitted to standby databases to reduce network traffic and improve redo transport performance. Because transport is faster, customers can achieve a lower Recovery Point Objective (RPO). Compression and decompression consume CPU on both primary and standby instances, so ensure adequate CPU capacity before enabling. Enable the feature by setting the redo_compression parameter in the instance Parameter Group; it supports mounted and read replicas and requires Oracle Enterprise Edition with Oracle Advanced Compression licensing.

Amazon RDS Supports MariaDB 11.8 with Vector Engine

🚀 Amazon RDS for MariaDB now supports MariaDB 11.8 (minor 11.8.3), the community's latest long-term maintenance release. The update introduces MariaDB Vector, enabling storage of vector embeddings and use of retrieval-augmented generation (RAG) directly in the managed database. It also adds controls to limit maximum temporary file and table sizes to better manage storage. You can upgrade manually, via snapshot restore, or with Amazon RDS Managed Blue/Green deployments; 11.8 is available in all regions where RDS MariaDB is offered.

Amazon RDS for PostgreSQL Adds Delayed Read Replicas

🕒 Amazon RDS for PostgreSQL now supports delayed read replicas, allowing you to specify a minimum time period for a replica to intentionally lag behind its source. This configurable time buffer helps protect against human errors such as accidental table drops or unwanted data modifications by preserving a recoverable replica state. In recovery workflows you can pause replication before problematic changes are applied, resume replication to a specific log position, and promote the replica as the new primary to achieve faster recovery than lengthy point-in-time restores.

Amazon RDS for Db2 Adds Support for Read Replicas Now

🔁 Amazon RDS for Db2 now supports read replicas, allowing customers to add up to three replicas per instance to offload read-only workloads and reduce load on the primary database. Replicas can be created in the same Region or across Regions and use asynchronous replication so read queries do not impact the writer. You can promote a replica for disaster recovery to enable read/write operations. Note that IBM Db2 licenses are required for all replica vCPUs; customers may use On‑Demand licenses from the AWS Marketplace or BYOL.

Amazon RDS for SQL Server: Kerberos via Self-Managed AD

🔐 Amazon Relational Database Service (RDS) for SQL Server now supports Kerberos authentication when instances are joined to a self-managed Microsoft Active Directory. Previously, Kerberos integration required AWS Managed Microsoft AD; customers can now enable Kerberos authentication with their existing on-premises or self-managed AD environments. This change simplifies migrations and preserves enterprise identity configurations while continuing to support existing integrations with AWS Managed AD. The feature is available in all AWS Commercial and AWS GovCloud (US) Regions.

Amazon RDS io2 Block Express Now in AWS GovCloud Regions

🔒 Amazon announced that Amazon RDS io2 Block Express volumes are now available in AWS GovCloud (US‑West) and AWS GovCloud (US‑East) Regions. These volumes provide consistent sub‑millisecond latency and industry‑leading outlier latency control for mission‑critical database workloads. io2 Block Express supports up to 256,000 Provisioned IOPS, 4,000 MB/s throughput, 64 TiB volumes, and 99.999% durability. Customers can upgrade from io1 without downtime using the ModifyDBInstance API and modify existing io1, gp2, or gp3 volumes in the RDS Management Console.
