# Supported features in Amazon RDS by AWS Region and DB engine
<a name="Concepts.RDSFeaturesRegionsDBEngines.grids"></a>

Support for Amazon RDS features and options varies across AWS Regions and specific versions of each DB engine. To identify RDS DB engine version support and availability in a given AWS Region, you can use the following sections.

Amazon RDS features are different from engine-native features and options. For more information on engine-native features and options, see [Engine-native features.](Concepts.RDS_Fea_Regions_DB-eng.Feature.EngineNativeFeatures.md)

## Table conventions
<a name="Concepts.RDS_Fea_Regions_DB-eng.Feature.TableConventions"></a>

The tables in the feature sections use these patterns to specify version numbers and level of availability:
+  **Version x.y** – The specific version alone is available. 
+ **Version x.y and higher** – The specified version and all higher minor versions of its major version are supported. For example, "version 10.11 and higher" means that versions 10.11, 10.11.1, and 10.12 are available.

## Feature quick reference
<a name="Concepts.RDS_Fea_Regions_DB-eng.Feature.QuickReferenceTable"></a>

The following quick reference table lists each feature and available RDS DB engine. Region and specific version availability appears in the later feature sections.
