Amazon Aurora with PostgreSQL Compatibility now supports PostgreSQL major version 10.5 , and is available in the US East (N. Virginia, Ohio), US West (Oregon), Europe (Ireland), Asia Pacific (Tokyo), and Asia Pacific (Seoul) Regions.

Amazon Aurora with PostgreSQL Compatibility version 10.5 adds support for Query Plan Management, a new feature that allows you to control how and when query execution plans change. Query plan management allows you to prevent plan regressions when the database system or environment changes, and allows you to control when and whether the optimizer can use new plans.

This release includes all patches from the PostgreSQL 10.1 , PostgreSQL 10.2 , PostgreSQL 10.3 , PostgreSQL 10.4, and PostgreSQL 10.5 minor versions. It also includes all extensions that are supported in the Amazon Aurora with PostgreSQL Compatibility 9.6 release.

To use the new version, you can create an Amazon Aurora with PostgreSQL Compatibility database instance with just a few clicks in the AWS Management Console . You can also create an Amazon Aurora with PostgreSQL Compatibility 10.5 read replica using an RDS for PostgreSQL 10.5 master instance, and then fail over your connections and applications to Aurora when ready. Learn more about migrating to Aurora PostgreSQL 10.5 in the Amazon RDS User Guide .

Amazon Aurora combines the performance and availability of high-end commercial databases with the simplicity and cost-effectiveness of open source databases. It provides up to three times better performance than the typical PostgreSQL database, together with increased scalability, durability, and security.

Amazon Aurora with PostgreSQL Compatibility now supports Query Plan Management in version 10.5, and is available in the US East (N. Virginia, Ohio), US West (Oregon), Europe (Ireland), Asia Pacific (Tokyo), and Asia Pacific (Seoul) Regions.

Amazon Aurora with PostgreSQL Compatibility version 10.5 adds support for Query Plan Management, a new feature that allows you to control how and when query execution plans change. Query plan management allows you to prevent plan regressions when the database system or environment changes, and allows you to control when and whether the optimizer can use new plans.

The quality and consistency of query optimization have a major impact on the performance and stability of any relational database management system (RDBMS). Query optimizers create a query execution plan for a SQL statement at a specific point in time. As conditions change, the optimizer might pick a different plan that makes performance worse. For example, changes in statistics, constraints, environment settings, query parameter bindings, and software upgrades can all cause the query optimizer to choose a different plan and lead to performance regression. Regression is a major concern for high-performance applications.

With query plan management, you can control execution plans for a set of statements that you want to manage. You can do the following:

• Improve plan stability by forcing the optimizer to choose from a small number of known, good plans.
• Optimize plans centrally and then distribute the best plans globally.
• Identify indexes that aren’t used and assess the impact of creating or dropping an index.
• Automatically detect a new minimum-cost plan discovered by the optimizer.
• Try new optimizer features with less risk, because you can choose to approve only the plan changes that improve performance.

AWS CodeStar now lets you automatically create a new Alexa Skill from within your Amazon Web Services (AWS) account. Previously, you needed to create the skill in the Alexa Skill console and link it with an AWS Lambda function in your AWS account. You would also need to manually register changes any time you updated your skill. These manual steps are no longer needed if you develop your Alexa Skills with CodeStar. To get started with Alexa skill templates on AWS CodeStar, go to our getting started guide to follow step by step instructions.

The AWS Solutions team has updated the AWS WAF Security Automations solution. AWS WAF is a web application firewall that enables customers to quickly create custom, application-specific rules that block common attack patterns that can affect application availability, or consume excessive resources.

AWS IoT Device Defender helps you keep connected devices secure. AWS IoT Device Defender alerts you whenever devices violate a user-defined behavior for security metrics gathered from devices and AWS IoT Core.

Today we are introducing partition placement groups, a new Amazon EC2 placement strategy that helps reduce the likelihood of correlated failures for large distributed and replicated workloads such as HDFS, HBase and Cassandra running on EC2. Partition placement groups spread EC2 instances across logical partitions and ensure that instances in different partitions do not share the same underlying hardware, thus containing the impact of hardware failure to a single partition. In addition, partition placement groups offer visibility into the partitions and allow topology aware applications to use this information to make intelligent data replication decisions, increasing data availability and durability.

Partition placement groups are available through AWS API and CLI to customers at no additional charge and is offered in US East (N. Virginia), US East (Ohio), US West (N. California), US West (Oregon), Asia Pacific (Mumbai), Asia Pacific (Seoul), Asia Pacific (Singapore), Asia Pacific (Sydney), Asia Pacific (Tokyo), Canada (Central), EU (Frankfurt), EU (Ireland), EU (London), EU (Paris), South America (São Paulo), China (Beijing) and China (Ningxia) regions.

To learn more about partition placement groups, see the user guide for EC2 Placement Groups.
