The client application or user sends a request ID to API Gateway that is generated in Step 1.The workflow also contains the following steps to check the status of the request at various stages: The requestor downloads the file using the URL.

The poller function sends a presigned URL to download the file from the S3 bucket to the requestor via Amazon Simple Email Service (Amazon SES). The poller function fetches results from Amazon S3. A third Lambda function, the poller, checks the status of the results in the DynamoDB table. Amazon Redshift exports the data to an S3 bucket. Writes the status back to the DynamoDB table. A second Lambda function, the request processor, performs following actions:. Writes a request to Amazon Simple Queue Service (Amazon SQS). Writes the status to an Amazon DynamoDB control table. The request receiver function performs the following actions:. API Gateway calls the request receiver Lambda function. The client application sends a request to API Gateway and gets a request ID as a response. The workflow contains the following steps: The following diagram illustrates our solution architecture: If partners aren’t using Amazon Redshift, they could use the solution described in this post. If Acme’s partners are using Amazon Redshift, cross-account data sharing could be a potential option. Acme wants to expose inventory information to partners in a cost-effective, secure way for inventory management process. The table PRODUCT_INVENTORY contains updated data. Near-real-time changes and updates to their inventory flow to Amazon Redshift, showing accurate availability of stock. The website maintains a self-service inventory, allowing different producers to send flowers and other materials to when their supplies are running low.Īcme uses Amazon Redshift as their data warehouse. In our use case, Acme sells flowers on its site and collects reviews from customers. We also provide an AWS CloudFormation template to help set up resources, available on the GitHub repo. The API performs asynchronous processing of user requests, sends user notifications, saves processed data in Amazon Simple Storage Service (Amazon S3), and returns a presigned URL for the user or application to download the dataset over HTTPS. In this post, we walk through setting up an application API using the Amazon Redshift Data API, AWS Lambda, and Amazon API Gateway. This pattern adds new challenges, like asynchronous processing, managing compute capacity, and scaling. OLAP APIs have a low call volume but large payload (100 MB to several GBs). However, OLAP (online analytical processing) has the ratio flipped. CREATE VIEW REDSHIFT SOFTWARE
APIs enable programs and applications to communicate with platforms and services, and can be designed to use REST (REpresentational State Transfer) as a software architecture style.ĪPIs in OLTP (online transaction processing) are called frequently (tens to hundreds of times per second), delivering small payloads (output) in the order of a few bytes to kilobytes. API (Application Programming Interface) is a design pattern used to expose a platform or application to another party.
