In this post, I describe a simple way to transfer data from ElastiCache for Redis clusters to other AWS database services using AWS Lambda functions.

This post summarizes what’s new in Amazon DocumentDB 4.0 and show you how to get started with Amazon DocumentDB 4.0 and transactions using an AWS Cloud9 environment.

In this post, we show you how to integrate Amazon DocumentDB with Amazon ES so you can run full text search queries over your Amazon DocumentDB data. Specifically, we show you how to use an AWS Lambda function to stream events from your Amazon DocumentDB cluster’s change stream to an Amazon ES domain so you can run full text search queries on the data.

The purpose of this post is to maintain continuous transactional replication from an on-premises or Amazon EC2 hosted SQL Server instance to an RDS for SQL Server DB instance in the Multi-AZ configuration when a host replacement occurs during maintenance activities or failover events.

We’re happy to announce that Amazon RDS for SQL Server now fully supports SQL Server Database Mail. Before this release, you needed to use a variety of work-arounds to enable Database Mail, such as using linked servers. With the release of Database Mail for SQL Server, you can enable Database Mail seamlessly by using database parameter groups. Database Mail is one of the heavily used features in Microsoft SQL Server. Database Mail enables you to send messages from the SQL Server to users by using a Simple Mail Transfer Protocol (SMTP) server. In this post, you learn how to configure Database Mail and send emails from an RDS for SQL Server DB instance via Amazon Simple Email Service (Amazon SES).

This post shows how you can perform a major upgrade for Aurora MySQL with minimal downtime using a blue-green deployment. This is useful for database administrators or DevOps team members responsible for the Aurora MySQL upgrades.

In this four-part series, we cover how to translate a relational data model to a graph data model using a small dataset containing airports and the air routes that connect them. Part one discussed the source data model and the motivation for moving to a graph model. Part two explored mapping our relational data model to a labeled property graph model. Part three covered the Resource Description Framework (RDF) data model. In this final post, we show how to use AWS DMS to copy data from our relational database to Neptune for both graph data models. You may wish to refer to the first three posts to review the source and target data models.

In this four-part series, we cover how to translate a relational data model to a graph data model using a small dataset containing airports and the air routes that connect them. Part one discussed the source data model and the motivation for moving to a graph model. Part two covered designing the property graph model. In this post, we explore mapping our relational data model to a Resource Description Framework (RDF) model. You may wish to refer to parts one and two of the series to review the model. In part four, we show how to use AWS DMS to copy data from a relational database to Neptune for both graph data models.
