Find and link similar entities in a knowledge graph using Amazon Neptune, Part 2: Vector similarity search

A knowledge graph combines data from many sources and links related entities. Because a knowledge graph is a gathering place for connected data, we expect many of its entities to be similar. When we find that two entities are similar to each other, we can materialize that fact as a relationship between them. In this […]

Minimize downtime when migrating your Oracle database to Amazon RDS for Oracle with transportable tablespaces and AWS DMS

Organizations want to move their critical Oracle workloads to Amazon Relational Database Service (Amazon RDS) for Oracle with minimal downtime and disruption to unlock the agility, elasticity, and innovation of the AWS Cloud. In this post, we explore options for migrating Oracle databases from a legacy platform (for example HPUX, AIX, SOLARIS and others) to […]

Tune replication performance with AWS DMS for an Amazon Kinesis Data Streams target endpoint – Part 3

In Part 1 of this series, we discussed the high-level architecture of multi-threaded full load and change data capture (CDC) settings to tune related parameters for better performance to replicate data to an Amazon Kinesis Data Streams target using AWS Database Migration Service (AWS DMS). In Part 2, we provided some examples of how we […]

Tune replication performance with AWS DMS for an Amazon Kinesis Data Streams target endpoint – Part 2

In Part 1 of this series, we discussed the architecture of multi-threaded full load and change data capture (CDC) settings, and considerations and best practices for configuring various parameters when replicating data using AWS Database Migration Service (AWS DMS) from a relational database system to Amazon Kinesis Data Streams. In this post, we demonstrate the […]

Tune replication performance with AWS DMS for an Amazon Kinesis Data Streams target endpoint – Part 1

AWS Database Migration Service (AWS DMS) makes it possible to replicate to Amazon Kinesis Data Streams from relational databases, data warehouses, NoSQL databases, and other types of data stores. You can use Kinesis data streams to collect and process large streams of data records in real time. Replicating data changes to a Kinesis data stream […]

Scale your relational database for SaaS, Part 2: Sharding and routing

This post is a continuation of our series on scaling your relational database for software as a service (SaaS). SaaS providers commonly use relational databases, such as Amazon Relational Database Service (Amazon RDS) and Amazon Aurora, in their solutions. In Part 1, we looked at some common ways to scale or optimize your relational database […]

Scale your relational database for SaaS, Part 1: Common scaling patterns

One of the challenges that software as a service (SaaS) providers face as their business grows is how to maintain their tenants’ experience. This includes ensuring acceptable performance and response times as the tenant base grows. Relational databases, such as Amazon Relational Database Service (Amazon RDS) and Amazon Aurora, are commonly used by SaaS providers. […]

Perform a side-by-side upgrade in AWS DMS by moving tasks to minimize business impact

You can use AWS Database Migration Service (AWS DMS) for many use cases, such as migrating from legacy or on-premises databases to managed cloud services, replicating ongoing data changes from online transaction processing (OLTP) databases such as Amazon Relational Database Service (Amazon RDS) to an online analytical processing (OLAP) data warehouse such as Amazon Redshift, […]

Use Single-AZ read replicas in Amazon RDS for SQL Server

In-Region read replicas and cross-Region read replicas are two popular read-scale availability options available in Amazon Relational Database Service (Amazon RDS) for SQL Server. Amazon RDS customers use read replicas to offload their analytical or read-intended transactional workloads from a primary database instance. Previously, read replicas required the primary database instance to be in a […]
