Overview

This recipe demonstarates how a file that is uploaded to Azure Storage gets reflected in PostgreSQL database when a notification is received on Azure Event Grid.

In this recipe, the Event grid schema is used from Azure Event Grid. GET Blob (file) is used to read the uploaded file by Azure Storage (Invoke) and Put Blob (file) is used to upload the file into Azure Storage (Invoke). The Data Import Operation is reflected in the PostgreSQL database (Invoke).

To use the recipe, you must install the recipe and configure the connection and other resources within the recipe. The recipe uses three adapters in two integration flows. The first integration flow (Oracle FTP Azure Storage Create Data) is a scheduled orchestration style integration which reads a file from FTP to upload the data in Azure Storage. The second integration flow (Oracle AEG Azure Storage PostgreSQL Data Sync) is an app-driven integration that syncs data from Azure Storage to PostgreSQL on receiving a notification on Azure Event Grid.
