Originally, the internal partitions that DynamoDB required to scale needed advanced specification from customers. - OutSystems 11 Documentation Therefore, the app's core functionality should be implemented in clearly defined steps and not, for instance, in Screen Actions. "Many customers were asking for features such as backup restores, event-driven programming, exports, and imports to and from S3," Akshat recalls. Its a very simple public RESTful API where you can obtain data about countries around the world. There's a high level of UX customization without having to be a designer. Calculate Values from Grouped Data. However, many applications might benefit from having one or more secondary (or alternate) keys available, to allow efficient access to data with attributes other than the primary key. So there we have it, in this first exercise weve looked at Gherkin, written a test scenario with Gherkin, implemented that test scenario using the BDD testing framework and ran several test scenarios inside a single screen. Inputs. When we run this test suite screen in a browser, we see the Scenario Outline repeatedly executed for all the records in the Static Entity: If one of the scenarios fails (for instance, we set the capital of Portugal to be New York), that specific test will fail, but the others will be executed, passing successfully. Amazon uses DynamoDB Streams and Amazon Kinesis Data Streams for DynamoDB to stream these changes, making them immediately available to other processes and services. Morgan Stanley, Bank of America, Barclays, and several international banks are facing what more than 10 analysts told Reuters was a poor outlook for banks trying to offload debt, of which $6.5 billion in leveraged loans and $3 billion each in secured and unsecured bonds are included in the purchase of Twitter.
