If you spend all day every day looking after hundreds of MySQL servers, the chances are that you have encountered this problem. And the chances are that if your servers are configured properly (i.e. you have the same configuration the master and the slaves), the error is almost certainly spurious and doesn’t mean what it says it means. So why does it happen? It isn’t entirely clear – it could be a consequence of a hardware glitch, in-flight data corruption in the network layer (though between TCP checksums, and binlog checksums it is vanishingly unlikely to pass through undetected), or ...

Feed: AWS Compute Blog. Author: Talia Nassi. Two common options when building applications are request-response and event-driven architecture. In request-response architecture, an application’s components communicate via API calls. The client sends a request and expects a response before performing the next task. In event-driven architecture, the client generates an event and can immediately move on to its next task. Different parts of the application then respond to the event as needed. In this post, you learn about reasons to consider moving from request-response architecture to an event-driven architecture. Challenges with request-response architecture When starting to a build a new application, ... Read More

Feed: AWS Compute Blog. Author: Talia Nassi. In event-driven architecture, services interact with each other through events. An event is something that happened in your application (for example, an item was put into a cart, a new order was placed). Events are JSON objects that tell you information about something that happened in your application. In event-driven architecture, each component of the application raises an event whenever anything changes. Other components listen and decide what to do with it and how they would like to react. When you build applications with event-driven architecture, you decouple your event sources and event ... Read More

Feed: AWS Compute Blog. Author: Talia Nassi. In modern application development, event-driven architecture is becoming more prominent because it can make building applications in the cloud easier. Event-driven architecture can allow you to decouple your services, which increases developer velocity, and can make it easier for you to debug applications. It also can help remove the bottleneck that occurs when features expand across different teams, which allows teams to progress more independently. One way to think about how an application works is as a system that reacts to events from other places, like from within your application. In this approach, ... Read More

Feed: AWS Big Data Blog. The AWS Well-Architected Data Analytics Lens provides a set of guiding principles for analytics applications on AWS. One of the best practices it talks about is build a central Data Catalog to store, share, and track metadata changes. AWS Glue provides a Data Catalog to fulfill this requirement. AWS Glue also provides crawlers that automatically discover datasets stored in multiple source systems, including Amazon Redshift, Amazon DynamoDB, Amazon Simple Storage Service (Amazon S3), MongoDB, Amazon DocumentDB (with MongoDB compatibility), and various other data stores using JDBC. A crawler extracts schemas of tables from these sources ... Read More
